ABSTRACT:
Base polymers devoid of non-linear optical properties exhibiting second order non-linear optical properties after the covalent attachment of tricyanovinyl groups to pendant side chains of the base polymer. Methods of preparing a polymer having second order non-linear optical properties by reacting the base polymers of the present invention with tetracyanoethylene in a basic solvent at elevated temperatures.
