    • The present invention provides a vulcanized rubber useful for heat resistant vibration-isolator which can be obtained by vulcanizing a composition comprising: (A) 110-175 parts by weight of an oil-extended copolymer comprising 100 parts by weight of an ethylene- alpha -olefin-non-conjugated diene copolymer rubber with an intrinsic viscosity [ eta ] of 3 dl/g or more and 10-75 parts by weight of an extender oil; (B) 5-20 parts by weight of a liquid diene polymer with melt viscosity of 100-3000 poises at 25 DEG C, per 100 parts by weight of an ethylene- alpha -olefin-non-conjugated diene copolymer rubber; and (C) 10-80 parts by weight of a reinforcing filler, per 100 parts by weight of an ethylene- alpha -olefin-non-conjugated diene copolymer rubber; with an organic peroxide. The vulcanized rubbers of the present invention have an excellent thermal stability and durability, a low dynamic spring constant, and an excellent processability; they are useful for heat resistant vibration-isolator rubber, and are most suitable for, for example, uses of vibration-isolator for automobiles for engine mount, strato mount, suspension bush, exhaust mount and the like, and uses of vibration-isolator for vehicles for railway, vehicles for construction, industrial instruments, and instruments for office-automation and the like.
