PURPOSE:To obtain a polyacetal resin composition having extremely excellent weathering (light) resistance, not causing problems such as occurrence of eye mucus from a nozzle during molding, change of color resulting from light deterioration and flow mark on the surface of a molded article. CONSTITUTION:100 pts.wt. of a polyacetal resin is mixed with one of 0.10-1.50 pts.wt. of a light stabilizer, 0.10-1.50 pts.wt. of a UV rays absorber, 0.10-3.0 pts.wt. of polyethylene glycol, 1.0-3.0 pts.wt. of a polyamide and 1.0-3.0 pts.wt. of an ethylene.vinyl alcohol copolymer and uniformly blended in a molten state. A polyacetal resin composition having extremely excellent weathering (light) resistance, not causing problems such as occurrence of eye mucus from a nozzle during molding, color change resulting from light deterioration and flow mark on the surface of a molded article is obtained. |
