Abstract: A process is disclosed for producing finely divided, water-insoluble aziridine polymers by polymerisation of aziridines, preferably ethylene imine, in the presence of cross-linking agents which contain at least two functional groups in at least one ether. Also disclosed are modified, water-insoluble aziridine polymers obtained by reacting finely divided, water-insoluble, cross-linked aziridine polymers in an aqueous medium with carbon bisulphide or formaldehyde and a nucleophilic agent from the group of the alkaline metal cyanides, primary amines, secondary amines, alkaline metal sulphites and alkaline metal phosphites. The invention also relates to the use of the modified and non-modified, finely divided, water-insoluble polymers for immobilising active substances, as absorbing agent for aldehydes, ketones and acids and for removing heavy metal ions from waste water.

Abstract: Paper, board and cardboard having high dry strength are produced by the addition of cationic, anionic and/or amphoteric starch as dry strength agents to the paper stock and drainage of the paper stock with sheet formation in the presence of cationic polymers as retention aids for starch, and cationic polymeric retention aids are used for increasing the retention of dry strength agents comprising cationic, anionic and/or amphoteric starch in the production of paper, board and cardboard.

Abstract: The invention relates to a method for producing paper, paperboard and cardboard by dehydrating paper material containing interfering substances in the presence of fixing agents. Reaction products are used as fixing agents. Said products are obtained by reacting polymers, containing amino and/or ammonium groups, from the group of of: polymers containing vinyl amino units, polyalkylene polyamines, polyamidoamines, polyamidoamines grafted with ethylene imine and optionally cross-linked, polydiallydldimethylammoniumchlorides: polymers containing dialkylaminoalkylacrylamide-units or dialkylaminoalkylmethacrylamide units and polyallylamines and dicyandiamide-formaldehyde-condensates, with reactive sizing agents for paper with a polymer/reactive sizing agent weight ratio of 15,000 : 1 to 1 : 1. The invention also relates to reaction products thus obtained and to their use as fixing agents for water soluble and water insoluble interfering substances in the production of paper, paperboard and cardboard from paper materials containing interfering substances.

Abstract: A process for fractionating water-soluble or water-dispersible amino-containing synthetic polymers having a broad molar mass distribution by ultrafiltration, wherein the polymer solution or dispersion to be fractionated is fed continuously into an ultrafiltration circulation with at least one ultrafiltration unit, and retentate having a narrower molar mass distribution and permeate are discharged continuously, in such a way that the ultrafiltration circulation is essentially in a steady state, the polymers obtainable by this process and their use.
