(57) [Summary] [Structure] Methyl methacrylate unit 35 to 98% by weight And a specific methacrylic acid ester unit 1 to 30% by weight And 75 to 95 parts by weight of a copolymer (A) consisting of 1 to 25% by weight of a specific maleimide unit and 0 to 10% by weight of another copolymerizable vinyl monomer unit, and an aromatic polycarbonate resin (B ) 5 to 25 parts by weight of a polymer composition. [Effect] Since the polymer composition of the present invention has a high glass transition point, excellent transparency, and good compatibility, a wide range of molding conditions can be selected. The polymer composition of the present invention can be suitably used for a film, a sheet material, and a molded article such as a lens and an optical disk by utilizing the above characteristics. |
