    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.

    摘要： Thermoplastic elastomer compositions having excellent flexibility, mechanical properties and extrusion moldability are produced by directly feeding a particulate olefinic copolymer rubber (A) and an olefinic plastic (B) to a continuous kneading extruder to carry out melt kneading and, downstream, feeding an organic peroxide to the extruder to carry out dynamic crosslinking, the ratio of the bulk density of the particulate olefinic copolymer rubber (A) to the bulk density of the olefinic plastic (B) being in the range 0.1 to 0.9.
