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: 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.
