PURPOSE:To obtain a composition capable of providing molded products excellent in impact resistance and mechanical properties and good in surface appearance and heat aging resistance by blending a specific polyoxymethylene resin with a thermoplastic polyurethane. CONSTITUTION:A polyoxymethylene resin composition is obtained by blending (A) 100 pts.wt. polyoxymethylene resin prepared by copolymerizing (A1) trioxane with (A2) at least one cyclic ether compound selected from ethylene oxide, 1,3-dioxolane, 1,3--dioxepane, 1,3,5-trioxepane and 1,3,6-trioxocane and (A3) a compound selected from phenyl glycidyl ether, styrene oxide and naphthyl glycidyl ether with (B) 1-150 pts.wt., preferably 5-100 pts.wt. thermoplastic polyurethane. The amounts of the respective copolymerized components in the component (A) based on 100 pts.wt. component (A1) are preferably within the ranges of 0.1-7 pts.wt. component (A2) and 0.01-5 pts.wt. component (A3). |
