Thermoplastic elastomer, composition therefor and production process thereof, as well as molded or otherwise formed product obtained from the thermoplastic elastomer |
摘要 |
Described is a thermoplastic elastomer comprising (A) 10-90 wt. % of polypropylene having substantially a syndiotactic structure, and (B) 90-10 wt. % of an ethylene-propylene-nonconjugated diene copolymer rubber and/or ethylene-propylene copolymer rubber, said (B) having been partially crosslinked. The elastomer according to the present invention is useful for obtaining formed products, particularly automotive bumper fascias, automotive mud guards and automotive trim skin material, which are excellent not only in flexibility, rubber elasticity and mechanical strength but also in external appearance and touch, and are substantially free from bleeding and fogging.
