摘要： Described is a rubbery copolymer of ethylene, propylene and a nonconjugated polyene, wherein the ethylene/propylene molar ratio is 78/22 to 97/3 and the total content of propylene and nonconjugated polyene is 6 to 30 mole %, and is a vulcanizable rubber composition comprising said copolymer.
The rubber composition of the present invention yields vulcanized products excellent in tensile strength, heat resistance, oil resistance, compression set resistance and flex behavior. The vulcanized products can be used as automobile parts and other articles such as socket covers, heat resistant hoses, electric wires, condenser caps, heat resistant belts, vibration-proof rubbers, hoses, weather strips, seal sponges, black side wall of tires, etc.
