摘要： A copolymer comprising a structural unit (I) derived from a phosphonate monomer (1) such as diethyl methacryloyloxymethyl phosphonate and diethyl 2-methacryloyloxyethyl phosphonate, a structural unit (II) derived from a radical polymerizable monomer (2) such as methacrylic acid, acrylic acid, 8-tricyclo[5.2.1.0 2,6 ]decanyl methacrylate, and t-butyl methacrylate, and a structural unit (III) derived from methyl methacrylate, the content of phosphorus atoms derived from the phosphonate monomer (1) being not less than 1.0% by mass and less than 2.0% by mass relative to the mass of the copolymer, and a formed article comprising the copolymer.

摘要： A methacrylic resin [1] having a triad syndiotacticity (rr) of not less than 65% and a methacrylic resin [2] having a triad syndiotacticity (rr) of 45 to 58% are melt kneaded in a mass ratio of the methacrylic resin [1]/the methacrylic resin [2] of 40/60 to 70/30, and further melt kneaded preferably with a polycarbonate resin in a ratio of 1 to 10 parts by mass of the polycarbonate resin to the total 100 parts by mass of the methacrylic resin [1] and the methacrylic resin [2] to obtain a methacrylic resin composition.
