    摘要： An olefin-based thermoplastic elastomer composition comprising a thermoplastic elastomer blended with other resins and rubbers is provided. The thermoplastic elastomer contains polypropylene resin and an olefin-based copolymer rubber, and optionally, a linear polyethylene resin, and the thermoplastic elastomer has been crosslinked to a gel content of 95% or higher. A polyolefin resin, an olefin-based copolymer rubber and a softening agent are further blended with optional inorganic filler to provide the olefin-based thermoplastic elastomer composition. This composition is excellent in oil resistance and extrudability, and well-adapted for use as an energy-saving, resources-saving elastomer in applications including surface or skin material in autoparts, industrial mechanical parts, electric and electronic parts, and construction materials.

    摘要： Disclouse is an olefin thermoplastic elastomer foamed product obtained by heating a foamable composition comprising a partially crosslinked thermoplastic elastomer composition (A), a specific olefin plastic (B) and a foaming agent (C) in specific proportions. The partially crosslinked thermoplastic elastomer (A) is obtained by dynamically heat-treating a mixture in the presence of organic peroxide, said mixture comprising specific proportions of a peroxide-crosslinkable copolymer rubber (a), which is a specific ethylene/.alpha.-olefin/nonconjugated diene copolymer rubber, and a peroxide-decomposable olefin plastic (b), which is a (co)polymer containing 50 to 100% by mol of an .alpha.-olefin of 3 to 20 carbon atoms and has a specific MFR. The olefin plastic (B) is a (co)polymer containing 50 to 100% by mol of an .alpha.-olefin of 2 to 20 carbon atoms and has a specific MFR. Also disclosed is a process for preparing the olefin thermoplastic elastomer foamed product. The foamed product of the invention is free from surface roughening caused by defoaming even when an expansion ratio is 2 or more times. Besides, the foamed product is soft to the touch and shows excellent heat resistance and weathering resistance. According to the process of the invention, the foamed product can be prepared through simplified steps with high productivity.
