Abstract: The invention relates to aqueous dispersions of water-soluble polymers of N-vinyl carboxylic acid amides that contain, as stabilizers, water-soluble, cross-linked graft polymers that can be obtained by the radically initiated polymerization of compounds with at least two ethylenically unsaturated double bonds in the presence of polyalkylene glycols. The invention also relates to a method for producing aqueous dispersions of water-soluble polymers of N-vinyl carboxylic acid amides by the radical polymerization of N-vinyl carboxylic acid amides in an aqueous medium and in the presence of said stabilizers, and to the use of the aqueous dispersions as dehydrators, flocculants, retention agents, wet-strength agents, dry-strength agents and as fixing agents in the production of paper.

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.
