Polyelectrolyte complexes of cationic and anionic polymers which consist of n (a) cationic condensates of (i) at least one amine and (ii) a crosslinking agent from the group consisting of epihalohydrins, bishalohydrins of diols, bishalohydrins of polyalkylene glycols, bishalohydrins of polytetrahydrofurans, alkylene dihalides, alkylene trihalides, bisepoxides, trisepoxides, tetraepoxides and/or mixtures of said compounds, and/or quaternized cationic condensates of (i) and (ii), and n (b) anionic compounds containing at least three anionic groups n and have a charge ratio between anionic and cationic polymers of from 0.01 to 20, and a process for the preparation of the polylectrolyte complexes by mixing the cationic condensates (a) with anionic compounds (b). |
