Title:
GRAFT COPOLYMER AND POLYACETAL RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2015120843
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polyacetal resin composition that has particularly excellent sliding characteristics regardless of the kind of or the magnitude of a load of an opposite material and to provide a molded body of the polyacetal resin composition.SOLUTION: A graft copolymer is composed of (A) a main chain comprising an ethylene/glycidyl methacrylate copolymer and (B) a side chain comprising (b-1) styrene and (b-2) one or more kinds selected from glycidyl methacrylate and 2-hydroxypropyl methacrylate. The graft copolymer is composed of 50-90 pts.wt. of the main chain (A) and 10-50 pts.wt. of the side chain (B). The polyacetal resin composition contains 3-50 pts.wt. of the graft copolymer and 0.1-20 pts.wt. of a lubricant, based on 100 pts.wt. of a polyacetal resin.
