Abstract: Methacrylate (co)polymers containing carbazolyl side groups contain or are composed of repeating units of the general formula (I) (I) where m is an integer of from 3 to 11. The novel methacrylate (co)polymers containing carbazolyl side groups can advantageously be used as photoconductors in photoconductive layers, in particular of electrophotographic recording elements.

Abstract: The invention relates to a process for the preparation of (meth)acrylate polymers containing pendant (side-chain) nonlinear-optical chromophores and having moelcular weights of between 5000 and 5,000,000, in which polymers of (meth)acryloyl chloride are reacted in a polymer-analogous reaction in solution with D- omega -aminoalkyl chromophores of the formula (I) in which D is an electron donor, A is an electron acceptor, R is H, alkyl or cycloalkyl, X are CH groups and/or N atoms and m is from 2 to 11. The polymers prepared according to the invention can be used in optical components.

Abstract: In order to prepare acrylate and/or methacrylate polymers containing lateral carbazolyl groups, polymers of acrylyl chloride and/or methacrylyl chloride are reacted in solution in a polymer-analogous reaction with alcoholates of N-( omega -hydroxyalkyl)carbazoles. The poly(meth)acrylates prepared in this way have good photoconductor properties and are advantageously suitable for use in electrophotographic recording elements.
