         This Amendment No. 9 (this "Amendment No. 9") to Schedule 13D relates
to the common stock, par value $.01 per share, of International Specialty
Products Inc., a Delaware corporation ("ISP"), and amends the statement on
Schedule 13D originally filed on July 3, 1991 by Samuel J. Heyman, GAF
Corporation, G-I Holdings, Inc., G Industries Corp. and GAF Fiberglass
Corporation (formerly known as GAF Chemicals Corporation), as amended by
Amendment No. 1 filed on January 9, 1997, Amendment No. 2 filed on April 1,
1998, Amendment No. 3 filed on July 24, 1998, Amendment No. 4 filed on August
25, 2000, Amendment No. 5 filed on April 6, 2001, Amendment No. 6 filed on
August 21, 2001, Amendment No. 7 filed on March 27, 2002 and Amendment No. 8
filed on July 9, 2002.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         The aggregate transaction consideration described below in Item 4 is
expected to be approximately $130 million. It is anticipated that the
transaction consideration would be paid out of available funds of ISP.

ITEM 4.  PURPOSE OF TRANSACTION.

         Item 4 is amended and supplemented to include the following
information:

         Going Private Transaction

         On November 7, 2002, ISP issued the Press Release included as Exhibit
E to this Schedule 13D, which is incorporated by reference herein.

         Mr. Heyman (the "Stockholder") and a Special Committee of the Board
of Directors of ISP have reached an agreement on a going private transaction
in which the holders of ISP's publicly traded shares would receive $10.30 in
cash per share. The agreement followed a determination by the Special
Committee that the transaction consideration is fair to ISP's public
shareholders. The Special Committee, which consists of ISP directors who are
not officers of ISP, has been negotiating with the Stockholder regarding his
previously announced proposal of $10 per share. Lehman Brothers Inc. served as
financial advisor to the Special Committee.

         The transaction is expected to proceed as a merger and is subject to
the approval by ISP's Board of Directors and execution of a definitive merger
agreement. ISP's Board of Directors is expected to meet to consider approval
of a definitive merger agreement within the next few days. If the merger
agreement is approved by ISP's Board of Directors as anticipated, completion
of the merger will be subject to certain closing conditions, including
approval by holders of a majority of ISP's shares and approval by holders of a
majority of the votes cast by holders of shares not beneficially owned by the
Stockholder or the directors or officers of ISP.

         The Stockholder beneficially owns approximately 80.9% of ISP's
outstanding shares of stock.

         It is anticipated that, upon consummation of the transaction, the ISP
common stock would be delisted from trading on the New York Stock Exchange and
deregistered with the Securities and Exchange Commission.

         Other than changes in the capitalization, corporate structure and/or
governing documents resulting from the transaction, and other than the
intention to cause the Board of Directors of ISP following consummation of the
proposed transaction to be comprised solely of the Stockholder and certain
members of ISP's Board of Directors who are also members of ISP's management,
the Stockholder has no present plans or proposals with respect to any other
action referred to in instructions (a) through (j) of Item 4 of the form of
Schedule 13D. The Stockholder expressly reserves the right to change its
business plans, operations and management arrangements with respect to ISP
based on future developments.  In addition, the Stockholder reserves the right
to make dispositions from time to time prior to the closing of the transaction
of shares of common stock owned by Heyman Joint Ventures II LLC (up to 114,336
shares) to the extent permitted by the transaction agreements and applicable
law.

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER

         Item 5(a) and (b) is amended and supplemented to include the
following information:

         (a), (b) As of the close of business on November 6, 2002, the
reporting persons may be deemed to beneficially own, in the aggregate,
52,567,240 shares of ISP common stock (of which 239,200 represent shares
underlying options awarded to the

during the past 60 days by any reporting person or, to the knowledge of the
reporting persons, any person disclosed in response to Item 2.

INTERNATIONAL SPECIALTY PRODUCTS SPECIAL COMMITTEE AND SAMUEL J. HEYMAN REACH
AGREEMENT ON GOING PRIVATE PROPOSAL AT PRICE OF $10.30 PER SHARE

         WAYNE, NJ - NOVEMBER 7, 2002 - International Specialty Products Inc.
(NYSE: ISP) announced today that a Special Committee of its Board of Directors
and its majority stockholder, Samuel J. Heyman, have reached an agreement on a
going private transaction in which the holders of ISP's publicly traded shares
would receive $10.30 in cash per share.

         The agreement followed a determination by the Special Committee that
the transaction consideration is fair to ISP's public shareholders. The
Special Committee, which consists of ISP directors who are not officers of
ISP, has been negotiating with Mr. Heyman regarding his previously announced
proposal of $10 per share. Lehman Brothers Inc. served as financial advisor to
the Special Committee.

         The transaction is expected to proceed as a merger and is subject to
the approval by ISP's Board of Directors and execution of a definitive merger
agreement. ISP's Board of Directors is expected to meet to consider approval
of a definitive merger agreement within the next few days. If the merger
agreement is approved by ISP's Board as anticipated, completion of the merger
will be subject to certain closing conditions, including approval by holders
of a majority of ISP's shares and holders of a majority of the votes cast by
holders of shares not beneficially owned by Mr. Heyman or the directors or
officers of ISP.

         The transaction has a value of approximately $130 million. Mr. Heyman
currently beneficially owns approximately 80.9% of ISP's outstanding shares of
stock.

                 ADDITIONAL INFORMATION AND WHERE TO FIND IT.

         In connection with the proposed transaction, ISP will file a proxy
statement with the SEC. Investors and security holders are advised to read the
proxy statement when it becomes available, because it will contain important
information. Investors and security holders may obtain a free copy of the
proxy statement (when available) and other documents filed by ISP with the SEC

Department, 1361 Alps Road, Wayne, New Jersey 07470, Telephone:

ownership of ISP common stock is set forth in the proxy statement, dated April
12, 2002, for ISP's 2002 annual meeting of stockholders, as filed with the SEC
