Abstract
The purpose of the present invention is to provide: a polyacetal resin composition which is excellent in terms of impact resistance, thermal stability, and releasability; and a process for producing the polyacetal resin composition. The polyacetal resin composition comprises 100 parts by mass of a polyacetal resin (A) in which the molecular chain has neither a crosslink nor a branch therein, 0.01-10.0 parts by mass of an antioxidant (B), 0.01-5.0 parts by mass of a nitrogenous compound (C), and 0.05-1.0 parts by mass of a fatty acid amide (D), and has a melt index, as measured in accordance with ISO 1133, of 0.5-1.5 g/10 min. A process for producing the polyacetal resin compositions is also provided.
