Abstract

The invention relates to a process for the preparation of (meth)acrylate polymers with side-chain, non-linear optical chromophores and molecular weights of from 5000 to 5000000, which comprises reacting polymers of (meth)acryloyl chloride in solution with D-.omega.-hydroxyalkyl chromophores of the formula (I) or the alcoholates thereof ##STR1## where D is an electron donor, PA1 A is an electron acceptor, PA1 X is CH and/or N, and m is from 2 to 11. The polymers can be used in optical components.
