Abstract
This invention provides novel polyoxyalkylene polymers which exhibit nonlinear optical response, and which have utility as a transparent optical component in electrooptic light modulator devices. An invention side chain liquid crystalline polyoxyalkylene polymer is illustrated by the structure: ##STR1##
Claims6

- m.sup.1 is an integer of at least 5;
- n is an integer between about 4-20;
- X.sup.1 is --NR.sup.1 --, --O-- or --S--;
- R.sup.1 is hydrogen or methyl;
- and
- Z.sup.1 is --NO.sub.2.
