Patent ID: 7030189

Claim:
A thermoplastic elastomer resin composition comprising: (A) 50 to 90% by weight of a urethane-based thermoplastic elastomer; (B) 5 to 45% by weight of a polar group-containing thermoplastic elastomer comprising a melt-kneaded mixture comprising (a), (b), (c) and at least one of (d) and (e), wherein (a)–(e) are as follows: (a) 100 parts by weight of a rubber elastomer; (b) at least one compound selected from the group consisting of: (b-1) 0.01 to 15 parts by weight of an unsaturated carboxylic acid or a derivative thereof, (b-2) 1 to 30 parts by weight of a liquid polybutadiene having at least one terminal hydroxyl group, and (b-3) 0.01 to 15 parts by weight of an unsaturated glycidyl group-containing compound or a derivative thereof; (c) 0.01 to 3.5 parts by weight of an organic peroxide; (d) 20 to 240 parts by weight of a non-aromatic-based softening agents for rubber; (e) 1 to 100 parts by weight of a peroxide-decomposing polyolefin resin; and (C) 5 to 45 % by weight of a thermoplastic elastomer.
