ABSTRACT:
This invention provides novel polymers which contain discrete photoconductive and electrooptic moieties. The moieties may exist as part of the main chain of the polymer or as pendant side chains. The polymers have utility as transparent photorefractive media in photorefractive devices.
An invention polymer where both the photoconductive and electrooptic moieties exist as pendant side chains is illustrated by the copolymer of the following structure: ##STR1##
