PROBLEM TO BE SOLVED: To provide a transparent plastic substrate plate having heat resistance and a small birefringence value, and excellent in molding processability and surface smoothness, and concretely, the plastic substrate plate for a liquid crystal touch panel, transparent electroconductive substrate plate and lens array.SOLUTION: This acrylic copolymer and the transparent plastic substrate plate consisting of the same are provided. The copolymer consists of (i) a recurring unit derived from a methacrylate monomer, (ii) a recurring unit derived from a vinylaromatic monomer and (iii) an acid anhydride recurring unit. |
