Abstract

Novel water-soluble homo- or copolymers are described which comprise 1,1-diallyl-3,4-dimethylenepyrrolidinium cations in the polymer and can additionally include 1,1-dialkyl-3,4-dimethylenepyrrolidinium cations. The polymers are prepared by first polymerizing a diallylammonium salt of the formula [(CH.sub.2 .dbd.CH--CH.sub.2).sub.2 NH.sub.2 ].sup.+ X.sup.- in which X.sup.- is the anion of any Bronstedt acid and, preferably, a halide, alone or together with an unsaturated comonomer, and reacting the resulting polymer or copolymer with a base and an allyl halide. The novel polymers are preferably used for treating textiles.
