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.
L'invention concerne des polymères cationiques modifiés pouvant être obtenus par réaction de (a) composés polymères hydrosolubles contenant des groupes NH avec (b) des composés au moins bifonctionnels vis-à-vis des groupes NH, contenant au moins un radical alkyle ou alcényle à 8 atomes de carbone, et comme groupe fonctionnel un groupe halohydrine, époxyde, carboxyle, chloroformiate ou isocyanate, ou un atome d'halogène. L'invention concerne également un procédé de préparation desdits polymères par réaction des composés des groupes (a) et (b), ainsi que l'utilisation desdits polymères cationiques modifiés comme agents de fixation pour des impuretés contenues dans la pâte à papier, lors de la fabrication de papier.
