Abstract
A polyoxymethylene resin composition which comprises (A) 70-99.89% by weight of a polyoxymethylene resin, (B) 0.1-20% by weight of at least one ethylene-substituted vinyl copolymer having a melting point of 40-80° C. and prepared by polymerization using a radical polymerization catalyst, a chromium-containing catalyst or a Ziegler catalyst, and (C) 0.01-10% by weight of at least one liquid ethylene-&agr;-olefin random copolymer. The resin composition of the present invention is small in friction coefficient and excellent in abrasion resistance under high load and high temperature against noncrystalline resins.
