ABSTRACT:
Crosslinked polymer layers having nonlinear optical properties are produced by a process in which (A) diallyl esters of aromatic dicarboxylic acids or mixtures thereof with monoallyl monoalkyl esters of aromatic dicarboxylic acids are copolymerized with compounds having nonlinear optical activities and containing groups capable of polymerization or (B) prepolymers of diallyl esters of aromatic dicarboxylic acids or prepolymers of mixtures of diallyl esters of aromatic dicarboxylic acids and monoallyl monoalkyl esters of aromatic dicarboxylic acids are mixed with compounds having nonlinear optical activity and with or without polymerizable groups (=guest/host system), applied to a substrate and, after orientation in an electric field above 50.degree. C., crosslinked in a reaction which is initiated thermally or by free radicals.
