Abstract
Described is a thermoplastic elastomer composition, which has excellent fusion bond property and is useful for the production of a formed composite product. The thermoplastic elastomer composition comprises (i) 3-100 parts by weight of an addition-polymerized thermoplastic block elastomer composed of polystyrene-polybutadiene blocks or polystyrene-polyisoprene blocks and (ii) 100 parts by weight of a thermoplastic polyurethane block elastomer. A formed composite product is composed of a formed body of a rigid synthetic resin and the thermoplastic elastomer composition.
Claims6
A formed composite product comprising a formed body of a rigid synthetic resin and a thermoplastic elastomer composition having excellent fusion bond properties and fusion-bonded on the formed body, wherein the thermoplastic elastomer composition consists essentially of
- (i) 3-100 parts by weight of an addition-polymerized thermoplastic block elastomer composed of polystyrene blocks and diene blocks selected from the group consisting of polybutadiene blocks and polyisoprene blocks;
- and
- (ii) 100 parts by weight of a thermoplastic polyurethane block elastomer, wherein the thermoplastic polyurethane block elastomer has a hard segment prepared from a diisocyanate and a short-chain glycol and a soft segment prepared from a diisocyanate and a long-chain polyol.
