ABSTRACT:
An optical material obtained by electrically polarizing a high polymer molded article obtained from a composition comprising a copolymer of vinylidene cyanide and at least one comonomer selected from vinyl compounds, other vinylidene compounds and dienes having uniformly dispersed therein from 0.1 to 70% by weight of an organic molecular crystal having nonlinear optical effects, with the total amount of the copolymer and the organic molecular crystal being 100% by weight. The optical material has excellent orientation of the organic molecular crystal, great nonlinear optical effects, and excellent moldability.
