Abstract
There is disclosed a process for producing a polyacetal resin composition, which comprises mixing (A) a polyacetal resin, (B) a thermoplastic polyurethane elastomer and (B) a polyhydric alcohol having at least three hydroxyl groups in the molecule, in molten state with shear, at a temperature of 180.degree. to 250.degree. C. The polyacetal resin composition produced by the above process gives injection-molded shaped articles showing various well-balanced physical properties such as tensile strength and elongation at break at weld portions, and impact resistance.
