    摘要: An olefinic thermoplastic elastomer composition which is excellent in mechanical properties and is substi­tutable for vulcanized rubbers is provided, which com­prises a mixture comprising (A) 40 - 95 % by weight of an oil-extended olefinic copolymer rubber comprising 100 parts by weight of an olefinic copolymer rubber having a Mooney viscosity (ML₁₊₄ 100°C) of 150 - 350 and 20 - 150 parts by weight of a mineral oil and (B) 5 - 60 % by weight of an olefinic plastic, said mixture being partially crosslinked by dynamic heat treatment in the presence of an organic peroxide. This composition gives superior molded articles free from bleeding of oil on the surface.
