ABSTRACT:
A rubber composition comprising (1) a partially hydrogenated copolymer rubber composed of 10 to 50% by weight of an acrylonitrile unit, 25 to 88% by weight of a hydrogenated conjugated diene unit and 2 to 25% by weight of a conjugated diene unit, and (2) a sulfur vulcanizer system. The composition can give vulcanizates having improved ozone cracking resistance and oil resistance.
