Abstract: A polyoxymethylene resin composition from which formaldehyde is generated in a reduced amount upon molding, without carrying out a stabilization treatment for stabilizing an unstable terminal group in a crude oxymethylene copolymer. A hindered phenol-type antioxidant agent and an ethylene-(methacrylic acid) copolymer resin or an ethylene-(acrylic acid) copolymer resin or a salt thereof are melted and kneaded together to produce a polyoxymethylene resin composition without carrying out a stabilization treatment for stabilizing an unstable terminal group in a crude oxymethylene copolymer for which a polymerization catalyst is deactivated after the completion of copolymerization, and in which the unstable terminal group is not yet stabilized. When the polyoxymethylene resin composition is extrusion-molded, the discoloration of a molded product or the deterioration in properties of the molded product can be prevented for a long period of time. The resulting polyoxymethylene resin composition is suitable for forming an extrusion-molded article.

Abstract: A polyacetal resin composition. An aliphatic polycarboxylic acid having four or more carbons and two or more carboxyl groups and a hindered-phenol antioxidant are incorporated into a polyacetal copolymer obtained by copolymerizing trioxane as a major monomer with a cyclic ether and/or cyclic formal each having at least one carbon-carbon bond as a comonomer using a specific heteropoly acid as a polymerization catalyst, adding, to the resultant reaction product, a compound which is any of the carbonates, hydrogen carbonates, and carboxylates of alkali metal elements or alkaline-earth metal elements, the hydrates of these, and the hydroxides of alkali metal elements or alkaline-earth metal elements, and melt-kneading the mixture to deactivate the polymerization catalyst.
