| 摘要 |
A copolymer containing a structural unit (I) derived from a phosphonate monomer (1) such as diethyl methacryloyloxymethyl phosphonate or diethyl 2-methacryloyloxyethyl phosphonate, a structural unit (II) derived from a radical-polymerizable monomer (2) such as methacrylic acid, acrylic acid, 8-tricyclo[5.2.1.02,6]decanyl methacrylate, or t-butyl methacrylate, and a structural unit (III) derived from methyl methacrylate, the contained amount of phosphorus atoms derived from the phosphonate monomer (1) being from 1.0 mass% to less than 2.0 mass% relative to the mass of the copolymer. A molded article containing this copolymer. |
