摘要：
A thermoplastic elastomer composition comprising (a) 100 wt. parts of a polyolefin resin, (b) 5 to 250 wt. parts of an ethylene-&agr;-olefin copolymer rubber in which the content of the &agr;-olefin units is at least 50 wt. %, and (c) 0 to 500 wt. parts of an ethylene-&agr;-olefin copolymer rubber in which the content of the &agr;-olefin units is less than 50 wt. %. This composition can provide a molded article which is hardly whitened when it is bent, and has good flexiblity.
