摘要：
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.
