Abstract
Novel polymeric compounds having utility in multiactive photoconductive insulating elements. Such elements have at least two layers comprising an aggregate photoconductive layer in electrical contact with a photoconductor-containing layer. The aggregate photoconductive layer comprises at least one novel polymeric compound having the structure: ##STR1## WHEREIN R.sub.1, and R.sub.3, 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; PA1 R.sub.2, and R.sub.4, 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; PA1 R.sub.5 and R.sub.6 which may be the same or different, represent hydrogen or an electron withdrawing group; PA1 R.sub.7 can represent oxy, imino, thio, oxycarbonyl, iminocarbonyl, carbonyldioxy, ureylene, carbonyloxycarbonyl, sulfonyl, iminosulfonyl, iminocarbonyloxy; PA1 Ar is an unsubstituted or a substituted arylene group wherein said substituent is an electron accepting group or an electron withdrawing group; PA1 a, b and c are whole numbers of from 1 to 25; PA1…
