Thermoplastic resin and optical lenses containing the resin

Abstract

According to the present invention, a thermoplastic resin comprising a constituent unit (A) derived from a monomer represented by the following general formula (1) can be provided. (In general formula (1), R1 to R12, Rk and Rp independently represent hydrogen atom, fluorine atom, chlorine atom, bromine atom, iodine atom, cycloalkyl group having 5 to 20 carbon atoms, cycloalkoxy group having 5 to 20 carbon atoms, aryl group having 6 to 20 carbon atoms, linear or branched alkyl group having 1 to 10 carbon atoms, alkenyl group having 2 to 10 carbon atoms, alkoxy group having 1 to 10 carbon atoms, heteroaryl group having 6 to 20 carbon atoms or aralkyl group having 7 to 20 carbon atoms containing one or more heterocyclic atoms selected from O, N and S, X and Y represent single bond or alkyl group having 1 to 5 carbon atoms, i and ii independently represent integers 0 to 4, K1 and K2 independently represent -OH, -COOH or -COORq, and Rq represents alkyl group having 1 to 5 carbon atoms).
