Abstract: Paper, board and cardboard are produced by draining paper stock containing interfering substances in the presence of fixing agents by a process in which the fixing agents used are reaction products which are obtainable by reacting amino- and/or ammonium-containing polymers selected from the group consisting of thepolymers containing vinylamine unitspolyalkylene polyaminespolyamidoaminesethyleneimine-grafted polyamidoamines which may be crosslinked,polydiallyldimethylammonium chloridespolymers containing dialkylaminoalkylacrylamide units or dialkylaminoalkylmethacrylamide units andpolyallylamines anddicyandiamide and formaldehyde condensateswith reactive sizes for paper in a weight ratio of polymer to reactive size of from 15,000:1 to 1:1, and the reaction products thus obtainable are used as fixing agents for water-soluble and for water-insoluble interfering substances in the production of paper, board and cardboard from paper stocks containing interfering substances.

Abstract: The invention relates to a method for producing water-soluble homopolymers and copolymers, comprising oligoalkylene-imine side chains of the general formula (I), wherein [AI]m, m, Y and x have the definitions given in claim 1, by radical homopolymerisation or copolymerisation of monomers A of the general formula (II), wherein [AI]m, m, n, Y and R have the definitions given in claim 1, in an aqueous reaction medium. The invention also relates to the homopolymers and copolymers obtained by this method and to their use as auxiliary agents in paper production.

Abstract: The invention relates to modified cationic polymers which can be obtained by reacting (a) water-soluble, polymeric compounds containing NH groups with (b) compounds which are at least bifunctional with regard to NH groups, which contain at least one alkyl radical or alkenyl radical having at least 8 C atoms, and which contain, as a functional group, a halohydrin, epoxide, carboxyl, chloroformate or isocyanate group or a halogen atom. The invention also relates to a method for producing the polymers by reacting the compounds of groups (a) and (b), and to the use of the modified cationic polymers during the production of paper as fixing agents for papermaking stock containing interfering substances.
