Document Type and Number:
WIPO Patent Application WO/2018/003233
Kind Code:
A1
Abstract:
Provided is a polyacetal resin composition suitable for providing a plate-shaped resin molded article that satisfies all of the following: high flatness, low shrinkage ratio anisotropy (high dimensional stability), high creep resistance, high impact strength, and excellent color stability during residence in the molder. The polyacetal resin composition for molding a plate-shaped molded article according to the present invention comprises: (A) 100 mass parts of a polyacetal resin having a melt index (according to ASTM D1238, 190℃, 2.16 kgf) of 2.0 g/10 min to 4.0 g/10 min; (B) 0.1 mass parts to 2 mass parts of a polyacetal copolymer that is a copolymer of (b1) trioxane, (b2) a compound having two to four cyclic ether units in each molecule, and (b3) a compound having one cyclic ether unit in each molecule, the polyacetal copolymer having a branched or crosslinked structure; and (C) 0.1 mass parts to 1 mass part of a hindered phenol antioxidant.
