Abstract
Disclosed are electron acceptor monomers of the formula: ##STR1## R' is hydrogen or methyl; X and Y are independently selected from the group consisting of --NO.sub.2, halogen, cyano and --CF.sub.3 ; Z is oxygen or dicyanomethylene; and a and b can range from 0 to 3; With the proviso that at least one of R is ##STR2## AND POLYMERS PREPARED THEREFROM. These monomers and polymers are suitable for use in electrophotographic devices and methods.
