ABSTRACT:
A rubber composition containing (A) a mixture obtained by mixing (a1) 100 parts by weight of a highly saturated, ethylenically unsaturated nitrile-conjugated diene copolymer rubber whose copolymer chain contains not more than 30% by weight of conjugated diene units, and (a2) from 10 to 100 parts by weight of an ethylenically unsaturated monomer containing at least one carboxyl group, at least a proportion of the at least one carboxyl group being metal substituted such that a molar ratio of the at least one carboxyl group to the metal falls within a range of from 1/0.5 to 1/3; (B) an organic peroxide; and (C) a fatty acid amide, from 0.2 to 15 parts by weight of the (B) organic peroxide and from 0.5 to 20 parts by weight of the (C) fatty acid amide being added to 100 parts by weight of the (A) mixture.
