ABSTRACT:
Disclosed is a thermoplastic elastomer composition containing 10-60 parts by weight of a non-crosslinkable crystalline polyolefin resin (A), 1-30 parts by weight of a specific propylene 1-butene random copolymer (B) and 89-10 parts by weight of an ethylene α-olefin non-conjugated polyene copolymer rubber (C) which is composed of ethylene, an α-olefin having 3-20 carbon atoms and a non-conjugated polyene, in such amounts that the total of the components (A), (B) and (C) is 100 parts by weight. The thermoplastic elastomer composition is dynamically crosslinked by an extruder. This thermoplastic elastomer is excellent in moldability and economic efficiency, and enables to obtain a molded body exhibiting sufficient adhesion strength to a vulcanized rubber or thermoplastic elastomer without the intermediation of an adhesive layer, as well as a lightweight molded body having sufficient hardness and rubber elasticity.
