Abstract

The present invention relates to nonlinear-optically active copolymers which are composed of a chromophore acrylate, a glycidyl-functional acrylate, and a further acrylate unit, and to polyadducts produced from them by crosslinking with a carboxyl-functional polyester. The nonlinear-optical copolymers of the present invention, and the polyadducts prepared from them, possess an orientation stability in the crosslinked state, and a thermal stability, which makes them highly suitable for producing electrooptical and photonic components.
