PROBLEM TO BE SOLVED: To provide a thermoplastic transparent resin excellent in balance of transparency, heat distortion resistance, heat decomposition resistance, mechanical properties, low water absorption, weather resistance, and light resistance. Provided is a plastic optical article having an excellent balance of transparency, heat distortion resistance, heat decomposition resistance, mechanical properties, low water absorption, weather resistance, light resistance and the like using the thermoplastic transparent resin. A structural unit (B mole) obtained by polymerizing a monomer composition containing at least one (meth) acrylic acid ester monomer and at least one aromatic vinyl monomer, and derived from an aromatic vinyl monomer. It is obtained by hydrogenating 70% or more of the aromatic double bond of the copolymer whose molar ratio (A / B) of the structural unit (A mole) derived from the (meth) acrylic acid ester monomer to 1) is 1-4. A thermoplastic transparent resin characterized by that. An optical article using the thermoplastic transparent resin. [Selection] None |
