    摘要: Provided is a methacrylic resin composition which comprises a copolymer produced by polymerizing monomer components including methyl methacrylate and an acrylic acid ester, wherein the contents of methyl methacrylate and the acrylic acid ester are 95.5% by weight or more and 4.5% by weight or less, respectively. A solution of the methacrylic resin composition in chloroform having a concentration of 0.5 g/50 ml has a reduced viscosity of 40 to 50 ml/g at 25°C, and the triad syndiotacticity in a methyl methacrylate unit chain is 47 to 51%. The resin composition is useful for injection molding.
