THERMOPLASTIC ELASTOMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a thermoplastic polyester elastomer composition which is excellent in heat and oil resistance, tough and flexible and excellent in texture, hand touch, scratch resistance and bending resistance. SOLUTION: This thermoplastic elastomer composition is obtained by blending 60-99.5 pts.wt. of a polyester-based thermoplastic elastomer and 40-0.5 pts.wt. of an ethylene-carbon monoxide copolymer, preferably a partially crosslinked ethylene-unsaturated carboxylic acid ester-carbon monoxide copolymer which has a gel fraction of 20-80% and optionally a plasticizer such as a phthalic acid ester.
