ABSTRACT:
The present invention provides novel polymerizable substituted amide compound which are derived from the isocyanate compounds and which are useful in the preparation of nonlinear optical materials. The polymerizable substituted amide compounds of the present invention are represented by the formula; ##STR1## wherein R and R.sup.1 respectively represent a hydrogen atom or a lower alkyl group, A represents --X--(CH.sub.2).sub.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.
