POLYACETAL RESIN COMPOSITION

摘要

PURPOSE:To provide a polyacetal resin composition having markedly excellent heat resistance and being nonproblematic in discoloration and photosensitization due to the antioxidant. CONSTITUTION:The composition is prepared by uniformly melt-kneading 100 pts.wt. polyacetal resin with 0.05-5.0 pts.wt. diene polymer and 0.01-5.0 pts.wt. melamine derivative and optionally at least one member selected from among 0.01-1.0 pt.wt. alkali metal or alkaline earth metal compound, 0.01-5.0 pts.wt. hydrazide derivative and 0.01-1.0 pt.wt. acid amide.
