Polymeric quaternary ammonium salts are provided in which the cationic units correspond to the formula in which R1, R2, R3 and R4 are identical or different from one another and denote optionally substituted alkyl, cycloalkyl or alkenyl with at most 20 carbon atoms, aryl or aralkyl, or (R1 and R2) and/or (R3 and R4), together with the nitrogen atom to which they are bonded, form an optionally substituted heterocyclic ring with 3 to 6 ring members, A1 is -(CH2)m-, in which m is a number from 1 to 20, which is optionally interrupted by at least one -S-, or -CH=CH- grouping or substituted by at least one hydroxyl, halogen, nitrile, alkyl, hydroxyalkyl, alkoxy, carboxyl or carbalkoxy or optionally by at least one substituted aryl or aralkyl radical; polyoxyalkylene;an aryl,aralkyl or cycloalkyl radical; or A1 forms together with the nitrogen atoms and at least one of the subst??uents bonded to each nitrogen atom a piperazine, 1,4-diaralicyclo-(2,2,2)-octane or dipyridyl grouping, and A2 is a diphenylene or a tetrahydronaphtha ?e radical. The new compounds can be used as dyeing and finishing agents, especially for dyeing textile materials, as dispersing agents and emulsifiers, as antistatic, antimicrobial and flocculating agents and as precipitants. |
