PROBLEM TO BE SOLVED: To obtain a thermoplastic elastomer having excellent flowability of the molten resin which allows a powder slash molding at lower mold temperatures than that of conventional resins. SOLUTION: This thermoplastic elastomer resin composition comprises a composition obtained by carrying out dynamic crosslinking by using (a) 100 pts.wt. of a block copolymer composed of at least two units of a polymer block A containing an aromatic vinyl compound as a main component and at least one unit of a polymer block B containing a conjugated diene compound as a main component and/or a hydrogenated block copolymer obtained by hydrogenating thereto, (b) 20-300 pts.wt. of a softening agent for a non-aromatic rubber, (c) 10-150 pts.wt. of a peroxide-decomposing type olefin-based resin, (d) 0.01-15 pts.wt. of an unsaturated glycidyl compound, (e) 0.01-15 pts.wt. of an unsaturated carboxylic acid or a derivative thereof, (f) 1-30 pts.wt. of a liquid polybutadiene and (g) 10-2,500 pts.wt. of a thermoplastic polyurethane resin having 10,000-500,000 number-average molecular weight. |
