ABSTRACT OF THE DISCLOSURE: The invention is concerned with polymers containing structural units of the general formula: Image wherein R1 is hydrogen or a methyl group, R2 is an alkyl or hydroxyalkyl containing 1 to 6 carbon atoms, R4 and R5 are the same or different and represent hydrogen, an acyl, sulfate or hydrochloric group, an alkyl containing 1 to 4 carbon atoms or a -CH2COOH group, with the proviso that R5 can represent an acyl, sulfate or hydrochloric group only when R4 is hydrogen, or R4 and R5 together with the nitrogen atom to which they are attached form a diazo group, Ar is p-phenylene, and x is 1 to 4. The polymers of the invention are advantageously used as ion exchangers, catalysts for chemical reactions, and for biological applications.
