Abstract

The invention relates to nonlinear-optically active copolymers, to crosslinked NLO polymer materials produced from them and having high orientation stability, and to electrooptical and photonic components comprising these polymer materials. The copolymers of the invention are of the general formula 1 ##STR1## in which W is preferably a chromophoric group of the general formula 2: ##STR2## The chromophores employed in accordance with the invention exhibit high thermal stability and so can be processed at elevated temperatures while retaining the optical activity.
