Abstract: The disclosure concerns a method of producing water-soluble condensates and addition products containing amino groups and possessing enhanced de-watering and retention properties in paper production. Between 5 and 95 wt % of the condensates or addition products are removed as a permeate from solutions of water-soluble condensates or addition products containing amino groups by ultrafiltration through membranes and the condensates or addition products containing amino groups are if necessary isolated more efficiently from the retentate. The high-molecular polymer components contained in the residue are used as retention, de-watering and fixing agents in paper production, as promotors in gluing paper with alkyl diketenes, as flocculents for sewage sludges, as adhesives in the production of composite films, as additives to hair and skin conditioners and as an agent for immobilising anionic active substances.
