PROBLEM TO BE SOLVED: To provide a polyacetal resin composition excellent in extrusion moldability, particularly enabling reducing the development of voids at the central part or whitening, among others whitening unfavorable in appearance. SOLUTION: The polyacetal resin composition for extrusion molding comprises 100 pts. wt. of a polyacetal resin, (A) 0.1-5 pt(s). wt. of polyethylene or an ethylene-acrylic compound copolymer, (B) 0.01-5 pt(s). wt. of a phenol with steric hindrance, (C) 0.01-7 pt(s). wt. of an amine-substituted triazine compound and (D) 0.004-5 pt(s). wt. of at least one metal-containing compound selected from alkali( alkaline earth ) metal hydroxides, inorganic acid salts and metal alkoxides. This composition has a melt index of 1.0-30.0 g/10min. A rodlike or plate-like molding extruded product is obtained by extruding the resin composition. COPYRIGHT: (C)2004,JPO
