<p><P>PROBLEM TO BE SOLVED: To provide a methacrylic resin composition excellent in flowability, heat resistance, mechanical strength and transparency. <P>SOLUTION: This methacrylic resin composition includes a copolymer (1) having a methyl methacrylate unit (a) and an alkyl (meth)acrylate unit (b) other than methyl methacrylate and having 50,000-250,000 weight-average molecular weight; and a copolymer (2) having a methyl methacrylate unit (a) and an alkyl (meth)acrylate unit (b) other than methyl methacrylate and having 6,000-40,000 weight-average molecular weight; includes neither dispersion stabilizer nor emulsifier; where the mass fraction of the unit (b) included in the copolymer (1) is less than the mass fraction of the unit (b) included in the copolymer (2). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
