Powdery thermoplastic elastomer composition and articles obtained by molding same |
摘要 |
A thermoplastic elastomer composition powder comprising a thermoplastic elastomer composition represented by the following (A), having a sphere-reduced average diameter of not more than 1.2 mm and a bulk specific gravity of not less than 0.38: (A) a thermoplastic elastomer composition comprising (a) 100 parts by weight of a polyolefin resin; (b) 20 to 250 parts by weight of a conjugated diene polymer of hydrogenated conjugated diene copolymer having a hydrogenation degree of not less than 70%, which is prepared by hydrogenating a conjugated diene-vinyl aromatic compound random copolymer in which the content of a vinyl aromatic compound unit is not more than 25% by weight; and (c) 0 to 500 parts by weight of an ethylene/alpha-olefin copolymer rubber. This powder can give a molded article having excellent appearance and flexibility, which does not cause whitening easily on bending, according to the powder molding method.
