PROBLEM TO BE SOLVED: To provide a heat-resistant thermoplastic elastomer resin composition endowed with strength, rigidity, and flexibility necessary for moldings, having an excellent heat resistance, and excellent in terms also of molding workability.SOLUTION: The provided heat-resistant thermoplastic elastomer resin composition includes, with respect to 100 pts.wt. of a thermoplastic elastomer resin composition consisting respectively of 40-95 wt.% and 60-5 wt.% of two types of polyester block copolymers (A) and (B) respectively possessing, as constituent components, a high-melting-point crystalline polymer segment (a3) formed by dicarboxylic acid components consisting of (a1) terephthalic acid or ester-forming derivative thereof and (a2) isophthalic acid, naphthalene-2,6-dicarboxylic acid, or dimeric acid and a low-melting-point polymer segment (a4) consisting of aliphatic polyether units and/or aliphatic polyester units, 0.1-15 pts.wt. of a glycidyl group-modified polyolefin resin (C) and 0.5-10 pts.wt. of a polyamide resin (D). |
