NITRILE GROUP-CONTAINING COPOLYMER RUBBER, CROSS-LINKABLE RUBBER COMPOSITION, AND CROSS-LINKED RUBBER

摘要

Provided is a copolymer rubber containing a nitrile group, which is characterized by having a hydroxyl group, a carboxyl group or a carbon-carbon double bond on a terminal carbon atom or on a carbon atom bound to a terminal carbon atom. The copolymer rubber containing a nitrile group according to the present invention is preferably produced by a metathesis reaction. According to the present invention, a copolymer rubber containing a nitrile group can be provided, which has excellent crosslinking performance.
