ABSTRACT:
A rubber composition comprising (i) a nitrile group-containing highly saturated copolymer rubber, which is a product obtained by hydrogenating the conjugated diene portion of an unsaturated nitrile-conjugated diene copolymer, and (ii) an ethylene-.alpha.-olefin-non-conjugated diene copolymer rubber. The highly saturated copolymer rubber has an alkylthio group having 12 to 16 carbon atoms, which include at least three tertiary carbon atoms, and has a sulfur atom which is directly bound to at least one of the tertiary carbon atoms; and the highly saturated copolymer. rubber further has a Mooney viscosity of 15 to 200 and an iodine value not larger than 80.
