To provide a polyacetal resin composition largely improved in creep resistance and toughness without impairing advantages of polyacetal resins such as high rigidity and excellent molding processability.
The polyacetal resin composition is prepared by blending, in (A) 100 pts.wt. of a linear polyacetal resin obtained by copolymerizing (a) 100 pts.wt. of 1,3,5-trioxane and (b) 0.1 to 20 pts.wt. of a cyclic ether compound, (B) 0.1 to 10 pts.wt. of a branched and/or crosslinked polyacetal resin obtained by copolymerizing (a) 100 pts.wt. of 1,3,5-trioxane, (b) 8 to 20 pts.wt. of a cyclic ether compound, and (c) 0.1 to 1 pt.wt. of a monofunctional and/or polyfunctional glycidyl ether compound, (C) 0.01 to 5 pts.wt. of a hindered phenolic antioxidant, (D) 0.05 to 0.15 pt.wt. of an amine-substituted triazine compound, and (E) 0.10 to 0.20 pt.wt. of an aliphatic compound.
