PROBLEM TO BE SOLVED: To obtain a resin compsn. excellent in sliding characteristics by melt mixing and kneading a polyacetal resin with a modified olefin polymer, an alkylene glycol polymer, an inorg. filler, and if desired a specific lubricant. SOLUTION: This compsn. is prepd. by melt mixing and kneading 100 pts.wt. polyacetal resin with 0.5-100 pts.wt. modified olefin polymer obtd. by modifying an olefin polymer with at least one compd. selected from among unsatd. carboxylic acids and their anhydrides and derivs., an alkylene glycol polymer having prim- or sec-amino groups and a number average mol.wt. of 400-500,000, and 0.1-20 pts.wt. inorg. filler, pref. at least one filler selected from among calcium carbonate, potassium titanate, barium carbonate, and zinc oxide. |
