Abstract: PROBLEM TO BE SOLVED: To efficiently carry out stabilization of a polyacetal subjected to oxidative decomposition and obtain a high-quality molding material, by mixing the polyacetal with a specific sterically hindering phenol ester of dialkylene glycol in an acting amount. SOLUTION: A polyacetal such as polyoxymethylene is mixed with preferably 0.05-2wt.% (based on polyacetal) sterically hindering phenol ester of dialkylene glycol represented by the formula to stabilize the polyacetal subjected to oxidative decomposition according to ordinary method.
