Abstract of the Disclosure Novel polymeric compounds having utility in multi- active photoconductive insulating elements. Such elements have at least two layers comprising an aggregate photoconduc- tive layer in electrical contact with a photoconductor- containing layer. The aggregate photoconductive layer comprises at least one novel polymeric compound having the structure: Image wherein R1, and R3, which may be the same or different, represent a substituted or unsubstituted alkyl group having from 1 to 18 carbon atoms or a substituted or unsubstituted aryl group; R2, and R4, which may be the same or different, represent an alkylene group having from 2 to 10 carbon atoms or a substituted or unsubstituted arylene group; R5 and R6 which may be the same or different, represent hydrogen or an electron withdrawing group; R7 can represent oxy, imino, thio, oxycarbonyl, iminocarbonyl, carbonyldioxy, ureylene, carbonyloxycarbonyl, sulfonyl, iminosulfonyl, iminocarbonyloxy; - 1 - Ar is an unsubstituted or a substituted arylene group wherein said substituent is an electron accepting, group or an electron withdrawing group; a, b and c are whole numbers of from 1 to 25; d is 0 or 1; and n is a whole number having a value of at least 2. -11-
