CONDENSATION POLYMERIC PHOTOCONDUCTORS CONTAINING PENDANT ARYLAMINES, PHOTOCONDUCTIVE COMPOSITIONS AND ELECTROPHOTOGRAPHIC ELEMENTS CONTAINING THESE PHOTOCONDUCTORS

摘要

Polymeric photoconductors comprise a condensation polymer backbone containing, as repeating units, the condensation residues of 1) a diacid and 2) an organic difunctional compound capable of undergoing condensation polymerization with said diacid, and an arylamine photoconductor group appended to at least one of said diacid or said organic difunctional compound residues. The polymeric photoconductors are useful in photoconductive compositions and electrophotographic elements.
