摘要
There is disclosed an organic nonlinear optical material which comprises a polymer having the following constitutional units, in amounts of 5 to 100 mole % of (I) and 0 to 95 mole % of (II), and a weight average molecular weight (Mw) of the polymer being 10,000 to 2,000,000. ##STR1## wherein the symbols represent the same meanings as defined in the specification. ##STR2## A nonlinear optical element has large nonlinear optical effect and yet is excellent in molding processability so that it can be widely applied to the filed of optical processings.
