PROBLEM TO BE SOLVED: To provide a polyoxymethylene resin composition is low in contraction anisotropy after molded, and is excellent in thermal stability. SOLUTION: This polyoxymethylene resin composition is characterized by compounding a polyoxymethylene copolymer comprising (A) 100 pts.wt. of a polyoxymethylene copolymer and (B) 0.01 to 7 pts.wt. of an amine-substituted triazine compound with (C) 0.01 to 5 pts.wt. of polyethylene glycol having an average mol.wt. of≥10,000. Preferably, the composition further contains a steric hindrance phenol and an alkali metal or alkaline earth metal compound. COPYRIGHT: (C)2008,JPO&INPIT
