Abstract
The present invention provides a polyoxymethylene resin composition which is excellent in wear resistance and is suitable as materials for various sliding parts. The composition comprises (A) 65-98.8% by weight of a polyoxymethylene resin, (B) 0.2-5.0% by weight of a polyfunctional isocyanate compound, (C) 0.5-20% by weight of an olefin polymer containing 30% by weight or more of ethylene and a functional group containing an active hydrogen, and (D) 0.2-10% by weight of polyethylene.

A wear resistant polyoxymethylene resin composition which comprises
- (A) 65-98.8% by weight based on the total weight of the composition of a polyoxymethylene resin,
- (B) 0.2-5% by weight based on the total weight of the composition of a trifunctional isocyanate compound,
- (C) 0.5-20% by weight based on the total weight of the composition of a graft olefin polymer which is obtained by grafting onto an olefin polymer containing 30% by weight or more of ethylene, a copolymer comprising a monomer having a functional group containing an active hydrogen and a comonomer, and
- (D) 0.2-10% by weight based on the total weight of the composition of polyethylene.
