ABSTRACT:
The present invention provides a polyacetal resin composition improved, when molded, in environmental stress cracking resistance and in the physical properties of the weld portion. Environmental stress cracking resistance and physical properties of the weld portion before a heat aging resistance test can be improved by adding, to 100 parts by weight of a polyacetal resin, 0.001 to 1.0 part by weight of a difatty acid alkaline earth metal salt produced using two or more kinds of fatty acid and an alkaline earth metal. Also, the physical properties of the weld portion after a heat aging resistance test can be improved by further adding particular fatty acid ester compounds.
