CROSSLINKABLE RUBBER COMPOSITION AND CROSSLINKED OBJECT

摘要

A crosslinkable rubber composition comprising (a) 100 parts by weight of a highly saturated nitrile copolymer rubber having units derived from a monoalkyl ester of an ethylenically unsaturated dicarboxylic acid, (b) 0.5 to 10 parts by weight of a polyamine crosslinking agent, and (c) 0.5 to 10 parts by weight of a basic crosslinking accelerator. Crosslinking the composition gives a crosslinked, highly saturated, nitrile copolymer rubber which is excellent in heat resistance, resistance to fatigue from flexing, elongation, etc. and is reduced in compression set.
