Patent

CA 2485954

The present invention relates to a water-soluble polymer dispersion comprising:a dispersed polymer made up of at least one water-soluble monomer A and at least one water-soluble cationic monomer B, at least one stabiliser C, and at least one cationic polyelectrolyte as co-stabiliser D. It also relates to a method of producing a polymer dispersion and to a paper-making process.

Cette invention a trait à une dispersion polymère hydrosoluble contenant un polymère dispersé, dérivé d'au moins un monomère hydrosoluble (A) et d'au moins un monomère cationique hydrosoluble (B), ainsi qu'au moins un agent de stabilisation (C) et au moins un polyélectrolyte cationique agissant comme agent de co-stabilisation (D). Elle porte également sur un procédé de production de ce polymère et sur une technique de fabrication de papier.
