ABSTRACT:
The invention is a series of amorphous copolymers which, used in association with a small molecule, provide photorefractive materials that can be used in optical signal processing. These copolymers contain an active non-linear optical group and a group which contributes to their photoconductivity. ##STR1## where: X is H, CH.sub.3, Cl or F
