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.
