CA 2335229

Aqueous solutions of polycationic polymers (P AB) containing quaternary ammonium groups in salt form as heteroatomic chain members or ring members of the polymer, wherein a part of the counter-ions to the quaternary cationic groups are anionic groups of anionic optical brighteners, containing at least one anionic group, are valuable multi- functional agents in papermaking.

Solutions aqueuses de polymères polycationiques (PAB) comprenant des groupes ammonium quaternaire sous forme de sels en tant qu'éléments de chaîne hétéroatomique ou éléments de noyau du polymère, une partie des contre-ions des groupes cationiques quaternaires étant des groupes anioniques d'éclaircissants optiques anioniques, lesdites solutions contenant au moins un groupe anionique et pouvant être mises en application avantageusement dans la fabrication du papier.
