摘要: A polyacetal resin composition which comprises (A) 100 parts by weight of a polyacetal resin, (B) 0.1 to 1.5 parts by weight of at least one kind selected from the group of light stabilizers represented by the following formula (1) ##STR1## wherein two X's are the same or different and each denotes a hydrogen atom or a methyl group, (C) 0.1 to 1.5 parts by weight of an ultraviolet light absorber, (D) 0.1 to 3 parts by weight of polyethylene, (E) 0.1 to 5 parts by weight of polyethylene glycol, and (F) 0.1 to 10 parts by weight of a polymer of a methacrylate ester. This polyacetal resin composition is excellent in weather resistance and molding processability.
