Abstract

There is described a process for the preparation of photocon-ductive polymeric films wherein a minor portion (from about 10 to about 25 percent by weight) of the polymeric material present therein is highly oriented and a major portion (from about 75 to 90 percent by weight) of polymeric material is randomly or only slightly oriented. Initially a photoconduc-tive polymeric film is prepared from a blend of major and minor polymer fractions wherein the weight average molecular weight of the minor fraction is at least four times the weight average molecular weight of the major polymer fraction or from
