    Abstract: Method for achieving free radical initiated copolymerization of an addition monomer having pendant therefrom a strong donor group with an addition monomer having pendant therefrom a strong acceptor group. Copolymers prepared according to this method can be represented by the following formula: ##STR1## wherein R is hydrogen or methyl;R' is hydrogen or methyl;R" is hydrogen or methyl;R'" is selected from the group consisting of --NO.sub.2, halogen, --CN and --CF.sub.3 ;X and Y are independently selected from the group consisting of hydrogen, chlorine, bromine, alkyl of 1 - 4 carbon atoms and phenyl;a and b can range from 0 - 4; andn and m can range from about 5 to about 95 percent.The polymeric compositions prepared according to this method are suitable for use in electrophotography either alone as the primary photoresponsive entity or in combination with other photoconductive materials.
