ABSTRACT:
Olefin thermoplastic elastomers which comprise a partially crosslinked thermoplastic elastomer comprising a crystalline polyolefin resin (A), a block copolymer (B) which is composed of a polymer block of styrene or its derivative and a specific isoprene polymer block, and an olefin rubber (C), and thermoplastic elastomer laminates, having a substrate formed from a specific olefin thermoplastic elastomer or a crystalline polyolefin resin and a skin layer formed from the above-mentioned olefin thermoplastic elastomer, which are excellent in mechanical strength, heat resistance, heat aging resistance, weathering resistance and scratch resistance have been provided by the present invention.
