Polymerizable substituted amide compound, polymer obtained therefrom and nonlinear optical material using the same

摘要

The present invention provides novel polymerizable substituted amide compounds which are derived from isocyanate compounds and which are useful in the preparation of nonlinear optical materials. The polymerizable substituted amide compound of the present invention represents by the formula; <IMAGE> [I] wherein R and R1 respectively represent a hydrogen atom or a lower alkyl group, A represents -X-(CH2)n- in which X represents an oxygen atom or -NH- and n is an integer of 1 to 6, and m shows 0 or 1. The present invention also provides a homo- or co-polymer derived from the polymerizable substituted amide compound. The present invention further provides a nonlinear optical composition containing the homo- or co-polymer.
