Abstract

For the preparation of acrylate and/or methacrylate polymers containing carbazolyl side groups, polymers of acryloyl chloride and/or of methacryloxyl chloride are subjected to a polymer-analogous reaction in solution with alcoholates of N-(.omega.-hydroxyalkyl)-carbazoles. The poly(meth)acrylates containing carbazolyl side groups and prepared in this manner have good photoconductor properties and can advantageously be used in electrophotographic recording elements.
