ABSTRACT:
A method for preparing poly-N-alkenylamines having the following formula (I) ##EQU1## WHERE A is a tertiary aromatic or heterocyclic amine, connected to a carbon atom through nitrogen, R and R' are similar or different hydrogen or lower alkyl, and n is the degree of polymerization, consisting in that the secondary aromatic or heterocyclic amines or their derivatives, for example, diphenylamine, carbazole, phenthiazine, phenoxazine, 3-chloro- and 3,6-dichlorocarbazole are treated with aldehydes having the formula (II) RR'CH-CH=O, where R and R.sup.1 are the substances specified above, or their polymers capable of depolymerizing in an acid medium, in the presence of acid catalysts, in organic solvents. The said polymers are prepared by a single-step process without the separation of any intermediate products; the products prepared possess photosensitive properties and can be used, for example, in electrophotography and related processes.
