Abstract

The nonlinear optically active copolymers according to the invention are polyadducts of at least one organic di- or polycyanate and a nonlinear optically active compound, i.e. a chromophore. These copolymers have outstanding thermal stability and are suitable for the fabrication of technically useful electro-optical and photonic components with long-term stability.
