PURPOSE:To obtain the subject composition, having an ultrafine and homogeneous crystal structure and relaxed internal stress and capable of providing products excellent in mechanical strength, surface appearance and heat aging resistance by blending a polyoxymethylene resin with an aliphatic polyether and/or aliphatic polyester. CONSTITUTION:A polyoxymethylene resin composition obtained by blending (A) 100 pts.wt. polyoxymethylene resin prepared by copolymerizing trioxane with a cyclic ether compound selected from ethylene oxide, 1,3-dioxolane, 1,3- dioxepane, 1,3,5-trioxepane and 1,3,6-trioxocane and a compound selected from phenyl glycidyl ether, styrene oxide and naphthyl glycidyl ether with (B) aliphatic polyether and/or (C) an aliphatic polyester in an amount of 0.01-20 pts.wt., preferably 0.05-10 pts.wt. |
