                  Independent Auditors' Report


The Board of Directors
Crompton Corporation:


We  have  audited  the  accompanying  statements  of
net  assets available  for  benefits (modified cash
basis)  of  the  Crompton Corporation  Employee
Savings Plan (the Plan) as of December  31, 2001  and
2000,  and the related statements of  changes  in
net assets available for benefits (modified cash
basis) for the years then ended.  These financial
statements are the responsibility of the  Plan's
management.  Our responsibility  is  to  express  an
opinion on these financial statements based on our
audits.


We  conducted  our  audits in accordance with
auditing  standards generally  accepted  in  the
United  States  of  America.   Those standards
require that we plan and perform the audit  to
obtain reasonable  assurance about whether the
financial statements  are free of material
misstatement.  An audit includes examining, on a test
basis,  evidence supporting the amounts and
disclosures  in the  financial statements.  An audit
also includes assessing  the accounting  principles
used and significant  estimates  made  by management,
as well as evaluating the overall financial statement
presentation.   We believe that our audits provide  a
reasonable basis for our opinion.

As   described   in  note  1,  these  financial
statements and supplemental schedules were prepared
on a modified cash basis  of accounting,  which is a
comprehensive basis of  accounting  other than  accounting
principles generally  accepted  in  the  United
States of America.

In  our  opinion,  the  financial statements
referred  to  above present  fairly,  in  all
material  respects,  the  net assets
available  for benefits (modified cash basis) of the
Plan  as  of December  31,  2001  and  2000, and the
changes  in  net  assets available  for benefits
(modified cash basis) for the years  then ended, on
the basis of accounting described in note 1.

Our  audits were performed for the purpose of forming
an  opinion on  the  financial statements taken as a
whole.  The accompanying supplemental  schedule of
assets (held at end of year)  (modified cash basis)
and schedule of nonexempt transactions as of December
31, 2001 are presented for the purpose of additional
analysis and are  not  a required part of the basic
financial statements,  but are  supplementary
information required  by  the  Department  of Labor's
Rules and Regulations for Reporting and Disclosure
under the  Employee  Retirement  Income  Security
Act  of  1974.  The supplemental  schedules  are
the responsibility  of the  Plan's management.   The
supplemental schedules have been  subjected  to the
auditing  procedures applied in  the  audit  of  the
basic financial statements and, in our opinion, are
fairly  stated in all   material  respects  in  relation
to  the basic  financial statements taken as a whole.

                          CROMPTON CORPORATION
                          EMPLOYEE SAVINGS PLAN

                      Notes to Financial Statements

                       December 31, 2001 and 2000


(1)  Description of the Plan

     The  following description of the Crompton Corporation  Employee
     Savings  Plan  (the  "Plan") provides only general  information.
     Participants  should  refer to the  Plan  document  for  a  more
     complete description of the Plan's provisions.

     The  Plan  is  intended to be a profit sharing plan meeting  the
     requirements  of  Section 401(a) of the  Internal  Revenue  Code
     ("IRC")  and  contains provisions meeting  the  requirements  of
     Sections 401(k) and 401(m) of the IRC.

     The  Plan  administrator  is the Crompton  Corporation  Employee
     Benefit  Committee.   Fidelity Investments is  the  trustee  and
     record keeper of the Plan.

     The  Plan  is  a defined contribution plan established  for  the
     purpose  of  encouraging  and assisting  eligible  employees  of
     Crompton  Corporation and subsidiary companies  in  following  a
     systematic  savings  program.   The  Plan  is  subject  to   the
     provisions  of  the Employee Retirement Income Security  Act  of
     1974 as amended (ERISA).

     Effective January 1, 2001, Crompton Corporation merged  the  OSi
     Specialties,  Inc.  401(k)  Savings and  Investment  Plan  ("OSi
     Plan"),   and   the  Crompton  Corporation  Individual   Account
     Retirement  Plan  ("IARP") into the Witco  Corporation  Employee
     Retirement Savings Plan ("Witco Plan"), with the successor  plan
     being named the Crompton Corporation Employee Savings Plan.

     The  Plan  utilizes the modified cash basis of  accounting  (see
     Note  2), whereas the OSi Plan and the IARP utilized the accrual
     basis  of  accounting. Transfers into the Plan in  January  2001
     from  the  IARP in the amount of $206,937,029 and from  the  OSi
     Plans  in the amount of $46,075,324 were recognized representing
     the  cash basis of the IARP and OSi Plan. The December 31,  2000
     financial  statements  for  the  IARP  recognized  $673,536   of
     employer  contributions receivable and $587,834  of  participant
     contributions receivable and the OSi Plan recognized $67,736  of
     employer  contributions receivable and $178,466  of  participant
     contributions. These contribution receivables to  the  IARP  and
     OSi   Plan   at   December  31,  2000  have  been  included   as
     contributions  in  the 2001 financial statements  of  the  Plan,
     consistent with the modified cash basis of accounting.

     Employees  are eligible to participate in the Plan if  they  are
     eligible to participate in the Witco Plan, OSi Plan, or IARP  as
     of  December  31,  2000  (whether or  not  participating).   All
     employees  hired  on or after January 1, 2001  are  eligible  to
     participate  in  the  Plan beginning on the  first  day  of  any
     calendar month following 30 days of service.

     Participant Contributions

     Each year, participants may contribute to the Plan, by means  of
     payroll deductions, a pre-tax contribution of up to 15% of their
     earnings, effective with the first payroll period which ends  on
     or  after  the date in which the employee becomes a participant,
     provided  that the total of pre-tax contributions (and after-tax
     contributions,  if  any) do not exceed 15% of the  participant's
     earnings.    Participants  may  change  the  rate   of   pre-tax
     contributions (and/or after-tax contributions, if  any)  at  any
     time.  Participant contributions are subject to Internal Revenue
     Service limitations, which was $10,500 in both 2001 and 2000.

     Participants  who completed an hour of service under  the  Witco
     Plan  on or before January 1, 2001, may contribute to the  Plan,
     by  means  of  payroll  deductions, after-tax  contributions  of
     between 0% and 10% of earnings, effective with the first payroll
     period  which  ends on or after the date in which  the  employee
     becomes a participant.

     Participants who completed an hour of service under the OSi Plan
     on  or  before January 1, 2001, may elect to contribute  to  the
     Plan  after-tax contributions at a rate of from 2 1/2% to 7 1/2%
     of compensation   for   the  Plan  year.   The   aggregate   of
     a participant's  after-tax contributions and pre-tax contributions
     at   any   time   may  not  exceed  15%  of  the   participant's
     compensation.


     Employer Contributions

     If a participant was eligible to participate in the Witco Plan
     on December 31, 2000, the Company's matching contribution is 50%
     of  the  first  6% of the participant's after-tax  contributions
     and/or pretax contributions.

     If  a participant was eligible to participate in the OSi Plan on
     December 31, 2000, the Company's matching contribution is 50% of
     the  first  7 1/2% of a participant's pre-tax contribution.  If a
     participant's pre-tax contribution does not equal or exceed 7 1/2%
     of the participant's earnings, the Company matches 50% of after-
     tax  contributions,  up  to a maximum matching  contribution  of
     after-tax contributions of 3 3/4%.

     If  a  participant was eligible to participate in  the  IARP  on
     December 31, 2000, or first completes any hour of service  after
     January 1, 2001, the Company's basic contribution is equal to 2%
     of  each  participant's  earnings (5% for Gustafson  employees).
     Additionally,  the  Company  makes a  supplemental  contribution
     equal to 2 1/2% of each participant's earnings (Gustafson employees
     are  not  eligible  to receive this supplemental  contribution.)
     The  Company may, by appropriate corporate action, increase  the
     supplemental contributions made by it for any Plan year (or part
     of a Plan year) to a higher percentage than 2 1/2%.


     Investments of Contributions

     Participants'  pre-tax  contributions, after-tax  contributions,
     employer  contributions  and  rollover  contributions   may   be
     invested  in whole percentages among the investment alternatives
     made  available by the Plan administrator, at the  direction  of
     the  participants.   Participants may  change  their  investment
     elections  with  respect to existing funds, as  well  as  future
     contributions, at any time.


     Vesting

     Each   participant's  pre-tax  contribution  account,  after-tax
     contribution  account and rollover account is 100% fully  vested
     at all times.  Participants' Company contributions vest based on
     years of service according to the following vesting schedule:


                 Years of Service     Vested Percentage

                       Less than 1         0%
                       1                  25%
                       2                  50%
                       3                  75%
                       4                 100%

     Each   participant  is  fully  (100%)  vested  in  his   Company
     contribution  account in the event of any of the following:  his
     attainment  of  normal  retirement age  while  employed  by  the
     Company;  his  death while an employee of the  Company;  upon  a
     change  in  control  of the Company while  an  employee  of  the
     Company; termination of the Plan or partial termination  of  the
     Plan  which  affects the participant; or complete discontinuance
     of employer contributions to the Plan.

     If  a  participant was eligible to participate in the Witco Plan
     on  December  31, 2000, he is at all times fully vested  in  the
     portion  of  his  Company contribution account  attributable  to
     qualified  non-elective contributions;  a  participant  who  had
     three  years of service or three years of participation  service
     on December 31, 2000 is fully vested in his Company contribution
     account upon completion of three years of participation service;
     a  participant is fully vested upon attainment of age  55  while
     still  employed by the Company; and a non-bargaining participant
     is fully vested in his Company contribution account in the event
     of his termination due to economic conditions.

     For  those participants who were eligible to participate in  the
     IARP on December 31, 2000, and any eligible employee hired on or
     after January 1, 2001, they are always fully vested in the basic
     Company contributions.


     Forfeitures

     In  the  event  a  participant who is not fully  vested  in  his
     Company  contribution account incurs a break  in  service,  that
     portion which is not vested is forfeited.  In the event  that  a
     participant  who  is  less  than  50%  vested  in  his   Company
     contribution account makes a voluntary withdrawal of his  after-
     tax   contribution   account,  any  portion   of   his   Company
     contribution  account  attributable  to  his  matched  after-tax
     contributions  in which he is not vested is forfeited.   Company
     contributions  and  the  earnings thereon  forfeited  under  the
     provisions  of  the  Plan  are  applied  to  pay  administrative
     expenses and/or reduce subsequent Company contributions required
     under the Plan.  In the event that contributions under the  Plan
     are discontinued or the Plan is terminated, the distributions of
     such  forfeitures not yet applied are to be credited ratably  to
     the  accounts  of  active participants.  At  December  31,  2001
     forfeited  nonvested accounts totaled $217,372.  These  accounts
     will be applied to reduce future employer contributions.


     Withdrawals and Distributions

     At  age  59 1/2 and thereafter, an active participant can  withdraw
     funds  from  the  vested balance of his  account  at  any  time.
     Before  age  59 1/2,  participants are permitted to  make  hardship
     withdrawals  provided  that  he  has  an  immediate  and   heavy
     financial  need,  and only if the participant cannot  meet  that
     need  from  any other source.  A participant is not entitled  to
     receive  a  hardship withdrawal until he has received all  other
     distributions  and  loans available under  all  qualified  plans
     maintained   by  the  Company.   Hardship  withdrawals   require
     approval by the Employee Benefits Committee.  The minimum amount
     that  can be withdrawn under a hardship withdrawal is the lesser
     of  $200  or the total amount available for withdrawal, and  may
     not  exceed  the amount of the financial need including  amounts
     necessary  to pay any Federal, state and local income  taxes  or
     penalties  reasonably expected to result from the  distribution,
     and  are  to be paid in one lump sum.  If a participant makes  a
     hardship  withdrawal,  he  is  not permitted  to  resume  making
     contributions  for a period of twelve months subsequent  to  the
     withdrawal.

     Upon termination of employment, death, or attainment of age 70 1/2,
     a  participant is entitled to receive the value of his after-tax
     contribution  account,  pre-tax contribution  account,  rollover
     account,  and  the  vested portion of his  Company  contribution
     account  in  the  form  of  a  single  lump  sum  cash  payment.
     Distributions  are  to be made as soon as practicable  following
     the  participant's termination of employment, provided  however,
     that  if  the value of a participant's vested balance is greater
     than  $5,000,  the distribution will not be made  prior  to  the
     participant's normal retirement age without his consent.

     Any participant eligible to participate in the Witco Plan as  of
     December  31,  2000,  may  withdraw from  the  Plan  his  entire
     supplementary   after-tax  contributions  and  interest   earned
     thereon,  however,  the participant is not permitted  to  resume
     making supplementary after-tax contributions for a period of six
     months subsequent to the withdrawal.


     Loans

     Participants may borrow a minimum of $1,000 up to a  maximum  of
     $50,000   or   50%  of  their  vested  account  balance.    Loan
     transactions  are treated as a transfer between  the  investment
     funds and the loan fund.  There are two types of loans available
     that  consist  of a general loan and a loan to buy  a  principal
     residence.   No  participant  may  have  more  than  two   loans
     outstanding  at  any given time.  The loans are secured  by  the
     balance in the participant's account and bear interest at a rate
     of  1% over prime as of the origination date of the loan.   Loan
     repayments  are  made automatically through payroll  deductions,
     with  a minimum loan term of six months, and not to exceed  five
     years, except for a loan for the purpose of purchasing a primary
     residence, in which case the loan may not exceed fifteen  years.
     Participants  who were members in the OSi Plan on  December  31,
     2000,  were previously able to obtain a loan for the purpose  of
     purchasing a primary residence, with terms not exceeding  thirty
     years.


(2)  Significant Accounting Policies

     Accounting Basis

     The  accompanying financial statements have been prepared  on  a
     modified basis of cash receipts and disbursements; consequently,
     contributions,  interest and the related assets  are  recognized
     when  received  rather  than  when  earned,  and  expenses   are
     recognized  when  paid  rather  than  when  the  obligation   is
     incurred.   Accordingly, the accompanying  financial  statements
     are  presented on a comprehensive basis of accounting other than
     generally accepted accounting principles.


     Investment Valuation and Income Recognition

     The  Plan's investments are stated at fair value except for  its
     benefit-responsive  investment contracts, which  are  valued  at
     contract  value  (Note 3).  Fair Value is determined  by  quoted
     market prices, if an active market exists, or redemption values,
     which  approximate  market value.  Shares of  mutual  funds  are
     valued at the net asset value of shares held by the Plan at year-
     end.  The Crompton Corporation Stock fund is valued at its year-
     end  closing price.  Participant loans are stated at cost, which
     approximates fair value.

     Net  appreciation  (depreciation) in fair value  of  investments
     includes  investments bought, sold, and held  during  the  year.
     Purchases  and sales of securities are recorded on a  trade-date
     basis.   Interest  income is recorded on an  accrual  basis  and
     dividends are recorded on the ex-dividend date.


     Use of Estimates

     The  preparation of financial statements requires management  to
     make  estimates and assumptions that affect the reported amounts
     of  assets  and liabilities and disclosure of contingent  assets
     and  liabilities at the date of the financial statements and the
     reported  changes  in  net assets available  for  plan  benefits
     during  the reporting period.  Actual results could differ  from
     those estimates.


     Plan Expenses

     All  Plan expenses may be paid by the Company, however,  if  not
     paid  by  the Company, may be charged to the Plan and paid  from
     available  forfeitures, or will be charged to  each  participant
     based  on  his  allocable interest in  the  Plan.   The  Company
     provides administrative and accounting services for the Plan  at
     no charge.


(3)  Investments

     The   funds  available  to  participants  for  investing   their
     contributions and the Company contributions include the Crompton
     Corporation  Stock fund, various mutual funds  which  invest  in
     various  diversified stocks and bonds, and a fund which  invests
     in benefit-responsive insurance contracts.

     The Blended Income fund invests in benefit-responsive guaranteed
     investment   contracts  ("GICs")  offered  by  major   insurance
     companies  and  other  approved financial  institutions  and  in
     certain types of fixed income securities.  These GICs are stated
     at  contract value by the Plan's trustee (Fidelity Investments),
     which  approximates  fair  value.   The  average  yield  on  the
     Company's  GICs  was 5.93% during 2001.  The crediting  interest
     rate  on these GICs was 2.43% at December 31, 2001.  The Blended
     Income Fund was not an investment option in 2000.

     The  fair value of the individual investments that represent  5%
     or more of the Plan's net assets are as follows:

                                               December 31
                                            2001          2000
          Blended Income Fund          $108,462,234   $ 36,061,254
          Fidelity Magellan Fund         59,998,453     38,212,541
          Fidelity Growth Company        53,386,397     30,342,721
          Fidelity Freedom 2010 Fund     33,884,276     12,650,655
          U.S. Equity Index              23,353,053             --
           Commingled Pool


     During  2001  and 2000, the Plan's investments (including  gains
     and  losses  on  investments bought and sold, as  well  as  held
     during the year) appreciated/(depreciated) in value as follows:

                                             December 31
                                         2001           2000
          Crompton Corporation
            Common Stock Fund      $   (815,921)   $ (1,181,176)
          Mutual Funds              (42,962,864)    (16,563,251)
                                   $(43,778,785)   $(17,744,427)


(4)  Party-in-Interest Transactions

     Fidelity   Investments,  Inc.,  the  company,  and  participants
     receiving  plan  loans  are parties-in-interest  as  defined  in
     Section  3(14) of ERISA.  During the years 2001 and 2000,  there
     were no prohibited party-in-interest transactions.


(5)  Income Tax Status

     The Internal Revenue Service ("IRS") has determined and informed
     that  Company by a letter dated December 14, 1995, that the Plan
     and  related  trust are designed in accordance  with  applicable
     sections  of the IRC.  Although the Plan has been amended  since
     receiving  the determination letter, the Plan Administrator  and
     the Plan's Tax counsel believe that the Plan is designed and  is
     currently  being  operated  in compliance  with  the  applicable
     requirements  of the IRC.  The Company applied  for  a  new  tax
     determination  in December, 2001, and is awaiting response  from
     the IRS.


(6)  Plan Termination

     The  Company by action of its Board of Directors may suspend the
     operation  of the Plan for any year by omitting all or  part  of
     the employer contributions.  While the Company has not expressed
     any  intent to discontinue, terminate or curtail the  Plan,  the
     Company  at its discretion, may terminate or amend the Plan  for
     any  reason  at  any time provided that no such  termination  or
     amendment shall permit any of the funds established pursuant  to
     this  Plan  to be used for any purpose other than the  exclusive
     benefit of the participating employees.  Upon termination of the
     Plan,  the  rights of members to the benefits accrued under  the
     Plan to the date of termination shall be non-forfeitable.


(7)  Subsequent Event - Plan Merger

     Effective  April 1, 2002, the Uniroyal Chemical  Company,  Inc.,
     Savings  Plan  A, was merged into the Crompton Employee  Savings
     Plan.   The Provisions and investment options of the Plan  as  a
     result of this merger have remained unchanged.

     Effective  June  1, 2002, the Uniroyal Chemical  Company,  Inc.,
     Savings  Plan  for  Salaried  Employees,  was  merged  into  the
     Crompton  Employee Savings Plan.  The provisions and  investment
     options  of  the Plan as a result of this merger  have  remained
     unchanged.

8.   Nonexempt Transactions

     There  were  unavoidable  delays by the  Company  in  submitting
     January  2001 employee contributions due to problems encountered
     as  a  result in the change of the Plan's record-keeping.  There
     were  also  unintentional delays by the  Company  in  submitting
     February  2001  and  March 2001 employee contributions  for  the
     Company's  subsidiary  Davis Standard Corporation  due  to  data
     processing   systems  complications.   The   Company   will   be
     reimbursing the Plan for lost earnings determined by an interest
     calculation  based on the number of days the contributions  were
     delayed.
