Patent ID: 7176269

Claim:
A curable composition comprising a silyl-containing ethylene/α-olefin/non-conjugated polyene random copolymer rubber (A1) which has a structural unit derived from a norbomene compound, represented by the following general formula [I] or [II], as the non-conjugated polyene with at least one specific vinyl group at the terminal, and containing a hydrolyzable silyl group, represented by general formula [III], and wherein, “n” is an integer of 0 to 10; R 1 is a hydrogen atom or an alkyl group of 1 to 10 carbon atoms; and R 2 is a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, wherein, R 3 is a hydrogen atom or an alkyl group of 1 to 10 carbon atoms, wherein, R is a monovalent hydrocarbon group of 1 to 12 carbon atoms; X is a hydrolyzable group selected from the group consisting of hydride, halogen, alkoxyl, acyloxy, ketoximate, amide, acid amide, aminoxy, mercapto, alkenyloxy, thioalkoxy and amino group; and “a” is an integer of 0 to 2, wherein the rubber (A1) is produced by hydrosilylation, whereby said ethylene/α-olefin/non-conjugated polyene random copolymer rubber is reacted with a silicon compound represented by the following general formula [IV] in the presence of a transition metal complex catalyst: where R and “a” are as defined above; and a compound (B), other than the rubber (A1), having a hydroxyl group and/or a hydrolyzable group.
