Polymer compounds, compositions, nonlinear optical elements and light modulators

Abstract

The object of this invention is to provide a polymer compound that improves filterability and exhibits excellent thermal stability by suppressing viscosity increase or gelation during heating; to provide a composition comprising the polymer compound; to provide a nonlinear optical element made using the above composition; and to provide an optical modulator having the above nonlinear optical element and operating based on the electro-optic effect. This invention relates to a polymer compound comprising at least one of the repeating units selected from the group consisting of repeating units represented by formula (1-1), repeating units represented by formula (1-2), and repeating units represented by formula (1-3).
