CA 2592586
The invention relates to water-in-water polymer dispersions containing a polymer A with a cationic monomer fraction of up to 60 wt. % and at least one polymer dispersant B, based on cationised dialkylaminoalkyl (meth)acrylamides with an average molecular weight of between 75,000 and 350,000 g/mol. The invention also relates to a method for producing said dispersions and to the use of the latter.
L'invention concerne une dispersion polymère eau dans eau contenant un polymère A comprenant une proportion de monomères cationiques inférieure ou égale à 60 % en poids, ainsi qu'au moins un agent de dispersion polymère B à base de dialkylaminoalkyl(méth)acrylamides cationisés présentant un poids moléculaire moyen compris entre 75 000 et 350 000 g/mol. L'invention concerne en outre un procédé de production et l'utilisation de cette dispersion.
