Abstract
A process for producing a polyoxymethylene-polyurethane type alloy, which comprises allowing a polyisocyanate compound, a short chain polyol with a molecular weight of 62 to 350, a long chain polyol with a number-average molecular weight of 400 to 5,000, and optionally additives to react with each other in the presence of at least one or polyoxymethylene polymers.
