ABSTRACT:
The ethylene/.alpha.-olefin
onconjugated polyene copolymer rubber composition of the present invention comprises in specified proportions a crystalline polyolefin resin (A) and an ethylene/.alpha.-olefin
onconjugated polyene copolymer rubber (B) composed of ethylene, an .alpha.-olefin having 3 to 20 carbon atoms and a specific branched chain polyene compound. The molar ratio of ethylene units to .alpha.-olefin units, iodine value and intrinsic viscosity rubber (B) are within respective specified ranges. This rubber composition is excellent in low temperature properties. When the above olefinic thermoplastic elastomer composition is partially or entirely crosslinked, a molding can be provided which is superior to the conventional vulcanized rubbers in low temperature properties, tensile strength, elongation at break and rubber properties.
