PURPOSE: To produce an element having high nonlinear susceptibility and high performance by incorporating one or more kinds of specified structures into at least one repeating unit.
CONSTITUTION: At least one repeating unit contains one or more kinds of structures expressed by formula I. In the formula I, Q is expressed by formula II or NC-N, Z is an aromatic hydrocarbon ring or aromatic heterocycle which may have substituents. As for the production of the polymer material for a nonlinear optical material containing a component containing a naphthoquinone methide dye above described, several methods are used. For example, the polymer material is produced by polymn. of monomers bonded with the naphthoquinone methide dye. As for the polymn. reaction, addition polymn. and polymn. condensation reaction are used. Diols, diamines, dicarboxylic acid, dicarboxylic acid esters, dicarboxylic acid chloride, dicarboxylic acid anhydride, diisocyanate and the like are used as the monomers for polymn. condensation.
