6380316, Apr 30, 2002
Filed:
Mar 2, 1999
Appl. No.:
09/260456
Inventors:
Maneesh Bahadur - Midland MI
David Yen-Lung Chung - Bellaire TX
Toshio Suzuki - Midland MI
Raymond Lee Tabler - Midland MI
Hsien-Chang Wang - Bellaire TX
Assignee:
Dow Corning Corporation - Midland MI
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C08F 800
US Classification:
525263, 525264, 525265, 525288
Abstract:
A copolymer of isobutylene with 0. 5 to 15 mole percent of a conjugated diene (i. e. , a butyl rubber) is reacted with a silane having both an alkenyl group as well as at least two silicon-bonded hydrolyzable group, the reaction taking place in the presence of a free-radical generator, to provide a modified copolymer having reactive silyl groups grafted thereto. The modified copolymer exhibits a reduced molecular weight relative to the starting copolymer and may be used to formulate moisture-curable sealants, caulks, adhesive and coatings.
