Polymers containing a reactive aromatic system in the side chain which consist of structural units of the general formula IV: <IMAGE> (IV) where R1 is hydrogen or CH3, R2 is alkyl containing 1 to 6 carbon atoms, R3 is an acyl or sulfonic group, Ar is a bifunctional aromatic residue, and X=1 to 4. Said polymers being subject to further treatment consisting of acid hydrolysis and subsequent modification, e.g., with chloroacetic acid, formaldehyde or diazotizing and coupling with a suitable passive component.
