BRANCHED POLYACETAL RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a resin material improved in impact resistance while maintaining various characteristics such as excellent appearance or rigidity possessed by the polyacetal resin. SOLUTION: This branched polyacetal resin composition is obtained by compounding (A) 100 pts.wt. of a branched polyacetal copolymer containing oxymethylene groups as main recurring units and represented by the following general formula (I) [wherein m and n denote each an integer of 0-5; (m+n) is 1-5; and R denotes a monovalent organic group having 40-1,000 molecular weight] with (B) 3-50 pts.wt. of an impact resistance improving agent selected from a thermoplastic polyurethane and a core-shell polymer.
