Abstract

PURPOSE: To obtain a polyacetal resin composition having improved surface processability, by etching the composition comprising a polyacetal and finely divided calcium carbonate with aqueous sulfuric acid and/or phosphoric acid.
CONSTITUTION: A composition comprising (A) 100pts.wt. of a polyacetal resin, (B) 3W33pts.wt. of finely divided calcium carbonate having an average particle size of 0.1W4μ, and (C) 0.1W10pts.wt. of an unsaturated polyester is etched with aqueous sulfuric and/or phosphoric acid having the composition in the shadowed area surrounded by the straight lines a, b, and c and the abscissa. According to the method, processabilities, e.g. surface specular properties and adhesion between decorative layer resins, and thermal stability in molding can be improved.
EFFECT: Weight and cost reduction of mechanical parts.
