(57) [Summary] (Modified) [PROBLEMS] To provide a polyacetal resin composition which can be used in an environment where a chemical is present and can be suitably used for precision molded parts. SOLUTION: When the dynamic viscoelasticity of a molded article produced by injection molding is evaluated, the storage elastic modulus (G ′ (-100) ) at −100 ° C. and the storage elastic modulus (G ′) at −50 ° C. (-50)) The polymer obtained by repeating the oxymethylene unit, wherein the value obtained by dividing by) is 2.4 or more and the crystallinity is in the range of 58% to 80%. With respect to 100 parts by weight of a polyacetal copolymer having a unit inserted therein and a terminal group comprising an alkoxy group, a hydroxyalkoxy group, or a formate group and having a number average molecular weight in the range of 10,000 to 1,000,000, an antioxidant, formaldehyde-reactive nitrogen A polyacetal resin composition comprising 0.01 to 5 parts by weight of at least one of a polymer or compound containing: formic acid scavenger, weather (light) stabilizer, and release (lubricating) agent. |
