摘要：
A rubber composition comprising (I) at least one copolymer rubber selected from the group consisting of ethylene-propylene copolymer rubber and an ethylene-propylene-nonconjugated diene copolymer rubber and (II) a decomposition product having an intrinsic viscosity of 0.02 - 0.60 dl/g as measured in xylene at 70°C obtained by subjecting at least one copolymer rubber selected from the group consisting of ethylene-propylene copolymer rubber and an ethylene-propylene-nonconjugated diene copolymer rubber to thermal degradation at 300° - 450°C in the presence of an inert gas. This rubber composition is effectively utilized to produce vulcanized rubber products of ethylene-propylene copolymer rubber and/or ethylene-propylene-nonconjugated diene copolymer rubber.
