PROBLEM TO BE SOLVED : To provide a polyacetal resin composition that hardly gives out a formaldehyde odor when molded and diffuses a very small amount of formaldehyde from a molded article thereof and exhibits a sharply enhanced sliding property. ?SOLUTION : The polyacetal resin composition comprises 100 pts.wt. of a polyacetal resin and, incorporated therewith, (A) 0.01-5 pts.wt. of a hindered phenol antioxidant, (B) 0.01-5 pts.wt. of an alkali/alkaline-earth metal salt of a carboxylic acid and/or an alkaline (earth) metal salt of a saturated fatty acid, (C) 0.01-5 pts.wt. of a hydrazide compound, (D) 0.1-20 pts.wt. of a graft copolymer of an olefin (co)polymer with a vinyl (co)polymer and/or an olefin polymer bearing a glycidyl group in its side chain and (E) 0.1-5 pts.wt. of a lubricant. ?COPYRIGHT : (C)2007, JPO&INPIT ?
