    Abstract: Disclosed is a method for producing aqueous polyelectrolyte complex dispersions by turbulently mixing aqueous anionic polymer solutions having a minimum charge density of 5 meq/g with aqueous cationic polymer solutions having a charge density of more than 4 meq/g. Also disclosed is the use of the obtained aqueous polyelectrolyte complex dispersions or the polyelectrolyte complexes isolated therefrom as a pulp additive for producing paper having an increased water resistance, as a fixing agent, flocculant and retention agent, dewatering agent for sludges, as an additive for detergents, adhesives, cosmetic products such as shampoos and hair conditioners, coating agents used for leather, textiles, cellulose fibers, cotton, glass, ceramics, and metals, and as a carrier and/or protective colloid for medicaments, agrochemicals, and in human and animal nutrition.

    Abstract: The process for producing multilayered sheetlike structures, particles or fibers comprises the steps of (a) applying a reactive polycarboxylic acid or one of its derivatives atop a sheetlike, particulate or fibrous carrier material already comprising, or previously provided with, groups reactive toward, capable of covalent bonding with, the polycarboxylic acid or one of its derivatives, (b) if appropriate heating the carrier material treated in step (a) to a temperature in the range from 60° C. to 130° C. and preferably to a temperature in the range from 80° C. to 120° C. to hasten, complete or further optimize the covalent bonds, (c) applying atop the carrier material a cellulose capable of covalent bonding with the polycarboxylic acid or its derivatives. The present invention further relates to the use of the present invention's process for production of multilayered sheetlike structures, particles or fibers for hydrophilicizing surfaces, in particular for adhesion promotion between hydrophobic and hydrophilic materials and for improving the washability of synthetic fibers, the surfaces which are hydrophilicized by the process forming the sheetlike, particulate or fibrous carrier material.
