Aqueous dispersions of predominantly anionically charged polyelectrolyte complexes, processes for their preparation and their use

摘要

Aqueous dispersions of predominantly anionically charged polyelectrolyte complexes of at least one water-soluble and / or water-swellable anionic polymer and at least one water-soluble cationic polymer, which are obtainable by free radical polymerization of ethylenically unsaturated, anionic monomers in an aqueous medium in the presence of at least one water-soluble cationic polymer, per mole of the overall anionic monomers used in the polymerization, from 0,5 to 49 mol -% of at least one cationic polymer is used, a process for the production of the aqueous dispersions by free-radical polymerization of ethylenically unsaturated, anionic monomers in an aqueous medium in the presence of at least one water-soluble cationic polymer, per mole of the overall anionic monomers used in the polymerization, from 0,5 to 49 mol -% of at least one cationic polymer is used and the use of the aqueous dispersions as thickeners for aqueous systems, as drainage -, - flocculants and retention agents and as a wet - and dry strength agents in the production of paper, as drainage aids for sludge, as an additive to detergents - and cleaners, as coating compositions, in dye liquors for the textile dyeing, as binders for fiber webs and in the finishing liquors.
