Abstract: The invention relates to a process for the preparation of (meth)acrylate polymers containing pendant (side-chain) nonlinear-optical chromophores and having moelcular weights of between 5000 and 5,000,000, in which polymers of (meth)acryloyl chloride are reacted in a polymer-analogous reaction in solution with D- omega -aminoalkyl chromophores of the formula (I) in which D is an electron donor, A is an electron acceptor, R is H, alkyl or cycloalkyl, X are CH groups and/or N atoms and m is from 2 to 11. The polymers prepared according to the invention can be used in optical components.

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.

Abstract: The invention relates to a process for making patterned (structured) polymer layers having non-linear optical properties wherein either organic compounds containing ethylenically unsaturated groups are subjected to free radical copolymerisation (A) with stilbene, azo or azomethine compounds containing ethylenically unsaturated groups and donor and acceptor groups, or organic compounds containing ethylenically unsaturated groups are subjected to free radical polymerisation and are mixed (B) with stilbene, azo or azomethine compounds containing ethylenically unsaturated groups and donor and acceptor groups, the copolymers (A) or mixtures (B) thus obtained are exposed imagewise to high-energy radiation, the unirradiated parts are removed, and the patterned polymer layers thus obtained are polarised in an electric field to orient the chromophoric structural units in the region of the glass transition temperature of the polymer and crosslinked in an applied electric field. Such patterned polymer layers are suitable for the production of polymeric waveguides in communications technology.
