THERMOPLASTIC ELASTOMER COMPOSITION AND ELASTOMER MOLDED BODY

摘要

Disclosed is a thermoplastic elastomer composition containing 30-85% by weight of a styrene block copolymer (A) and 70-15% by weight of an olefin-alkyl acrylate copolymer (B). The olefin-alkyl acrylate copolymer (B) is preferably a copolymer composed of 30-90% by weight of an olefin monomer unit, 10-70% by weight of an alkyl acrylate monomer unit and 0-10% by weight of a maleic anhydride monomer unit, and the styrene block copolymer (A) is preferably a styrene-isoprene block copolymer. This thermoplastic elastomer composition enables to obtain an elastomer molded body which is excellent in the balance among flexibility, oscillation damping and adhesion.
