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.
本发明涉及由色团丙烯酸酯、环氧丙烯酸酯和另一种丙烯酸酯单元组成的非线性光学活性共聚物,以及通过与羧基功能聚酯交联制备的聚加物。本发明的非线性光学共聚物及其制备的聚加物在交联状态下具有方向稳定性和热稳定性,使它们非常适合用于制造电光和光子元件。
