PURPOSE:To provide the titled composition having extremely remarkably improved mold releasability in injection molding, absolutely without lowering the original mechanical properties, thermal stability, and appearance of the molded article of the base resin, by adding a specific higher fatty acid to an acetal resin. CONSTITUTION:100pts.wt. of an acetal resin is compounded with 0.001-1pt.wt., preferably 0.005-0.5pts.wt. of a 22-32C higher fatty acid, preferably behenic acid, montanic acid, cerotic acid, lacceric acid, etc.
