THIN-WALL MOLDED ARTICLE OF BRANCHED POLYACETAL RESIN

摘要

To provide a thin-walled molded article of a polyacetal resin not only having an excellent rigidity but also retaining a good balance of excellent properties such as mechanical strength and toughness. ¢Constitutlon! A thin-walled molded article of a branched polyacetal resin, produced by molding a branched polyacetal copolymer comprising (A) 99.8 to 85.0% by weight of trioxane, (B) 0.1 to 10% by weight of a cyclic ether and/or a cyclic formal as a comonomer, and (C) 0.1 to 5% by weight of a diglycidyl compound, the molded article having an average wall thickness of 2 mm or less and a bending modulus of elasticity of 30000 kg/cm2 or more as measured according to ASTM D-790 (thickness of test piece: about 0.8 mm).
