POLYOXYMETHYLENE RESIN COMPOSITION

摘要

A polyoxymethylene resin composition comprising: (A) 70 to 99.89 wt.% of a polyoxymethylene resin, (B) 0.1 to 20 wt.% of at least one ethylene-substituted vinyl copolymer prepared by polymerization using a radical polymerization catalyst, a chromium-containing polymerization catalyst or a Ziegler catalyst and having a melting point of 40 to 80 DEG C, and (C) 0.01 to 10 wt.% of at least one liquid ethylene- alpha -olefin random copolymer. This composition exhibits a low coefficient of friction against noncrystalline resins under high load at high temperature and is excellent in wear resistance.
