POLYACETAL RESIN COMPOSITION

摘要

A polyacetal resin composition is prepared by meltkneading a polyacetal resin (A) (99 to 40 wt. %) with a thermoplastic polyurethane (B) (1 to 60 wt. %) in the presence of a polyisocyanate compound, a polyisothiocyanate compound or a dimer or trimer thereof (C) in an amount of 0.1 to 10 wt. % based on the total of A and B. The composition is capable of forming moldings that have high impact strength and flex resistance, are free from surface peeling and leave little, if any deposit in a mold. The composition is usefully employed as a material to form molded automotive parts.
