摘要： A curable rubber composition comprises of a silicone rubber (A) and an ethylene-.alpha.-olefin-polyene amorphous copolymer (B) containing as the polyene component a norbornene compound having at least one kind of vinyl terminal group represented by 5-vinyl-2-norbornene or 5-methylene-2-norbornene. The rubber composition is speedily cured, if said components (A) and (B) are mixed by the A/B mixing ratio of 98/2-2/98 (% by weight) and kneaded in the presence of an organic peroxide. A vulcanizate rubber excelling in mechanical strength, water resistance and thermal aging resistance can be manufactured from said composition, since its crosslink density can be enhanced without impairing processing properties. Additionally, said composition entails reduced mold fouling phenomenon in the molding operation. Vulcanizate rubber thereby obtained can be advantageously used as industrial parts and electric parts.
