摘要:
Provided is a methacrylic resin composition to be used for molding by means of a metallic mold having a plurality of nano-scale concavo-convex patterns on the surface thereof. The methacrylic resin composition comprises a methacrylic resin (A) having an MFR at 230°C under a load of 3.8 kg within the range of 0.1 to 50; and at least one component (B) selected from the group consisting of higher fatty acid esters, higher aliphatic alcohols, higher fatty acids, higher fatty acid amides, and higher fatty acid metal salts, wherein the content of the component (B) is 0.2 to 0.5 parts by weight with respect to 100 parts by weight of the methacrylic resin (A).

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.
