PURPOSE:To obtain a polyacetal resin composition improved in its coating properties and printability without impairing excellent characteristics of a polyacetal resin by blending the polyacetal resin with a specific (meth)acrylate- based copolymer. CONSTITUTION:A polyacetal resin composition is obtained by blending (A) 100 pts.wt. polyacetal resin with (B) 1-50 pts.wt., preferably 5-45 pts.wt., copolymer, prepared by copolymerizing (B1) 5-90wt.%, preferably 10-70wt.% unsaturated epoxy monomer (e.g. glycidyl acrylate or p-glycidylstyrene) with (B2) 10-95wt.%, preferably 20-80wt.% (meth)acrylate [e.g. polyoxyethylene mono(meth)acrylate] having a polyoxyalkylene group and (B3) 0-85wt.% copolymerizable other monomers (e.g. styrene or acrylonitrile) according to a solution polymerization method, a suspension polymerization method, or an emulsion polymerization methods, etc., and having 1000-300000, preferably 5000-250000 weight-average molecular weight. |
