ABSTRACT:
An oil-resistant rubber composition comprising 98 to 50 parts by weight of (1) a partially hydrogenated unsaturated nitrile/conjugated diene copolymer rubber in which at least 50% of units derived from the conjugated diene are hydrogenated, and 2 to 50 parts by weight of (2) a liquid copolymer having a number average molecular weight of 500 to 10,000 obtained by copolymerizing 10 to 80% by weight of a conjugated diene, 10 to 70% by weight of an unsaturated nitrile and 0 to 20% by weight of a vinyl monomer copolymerizable with these monomers, the total amount of the components (1) and (2) being 100 parts by weight.
