    • 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.
    • 用于实现自由基引发共聚合的方法,其具有从其侧向的强供体基团的加成单体与其上具有强受体基团的加成单体。 根据该方法制备的共聚物可以由下式表示:其中R是氢或甲基; R'是氢或甲基; R“是氢或甲基; R“选自-NO 2,卤素,-CN和-CF 3; X和Y独立地选自氢,氯,溴,1-4个碳原子的烷基和苯基; A和B可以从0-4开始; 而且N和M可以从约5到95%的范围。
