PROBLEM TO BE SOLVED: To provide a thermoplastic elastomer excellent in flexibility, weather resistance, heat resistance, low temperature characteristics, strength and molding processability, and an elastomer member consisting of the above composition, not requiring surface coating and excellent in scratch resistance. SOLUTION: This thermoplastic elastomer composition consists of the following (A), (B) and (C). (A) 100 pts.wt. polyurethane elastomer. (B) 1-900 pt.wt. copolymerized metallocene polyolefin of 8-30 wt.% 3-12 Cα-olefin comonomer with ethylene, having 0.86-0.94 density and 1.5-5.0 molecular weight distribution (Mw/Mn). (C) 3-100 pt.wt. modified polymer having carboxylic acid group or its derivative group, or epoxy group or its derivative group in its molecule. |
