Abstract: The invention relates to a process for making crosslinked polymer layers having non-linear optical (NLO) properties wherein diallyl esters of aromatic dicarboxylic acids or their mixtures with monoallyl monoalkyl esters of aromatic dicarboxylic acids are copolymerised with NLO-active compounds containing polymerisable groups 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 NLO-active compounds with or without polymerisable groups (= guest-host system), applied to a substrate, and, following orientation in an electric field above a temperature of 50@C, crosslinked in a reaction which is initiated thermally or by free radicals.
