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 (ML.sub.1+4 100.degree. C.) of 150-350 and 20-150 parts byw eight 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.

摘要： A blend which comprises a partially crosslinked product of a mixture of an oil-extended olefinic copolymer rubber comprising an olefinic copolymer rubber having a 100.degree. C. Mooney viscosity 150-350, a polyolefin resin, a selectively hydrogenated block copolymer, and a specific mineral oil type softening agent has excellent flexibility of less than 45 in Shore A hardness. The blend is not tacky, nor does the softening agent bleed. An anti-static agent for polyolefins and/or a higher fatty acid amide may be included in the composition.
