Abstract:
A concentrated and low viscosity aqueous dispersion comprising the water-soluble aqueous phase polymerizate of from 70% to 100% by weight of at least one water-soluble monomer A, from 0% to 30% by weight of at least one amphiphilic comonomer B, and from 0% to 30% by weight of at least one hydrophobic comonomer C, in the presence of at least one polymeric dispersant incompatible therewith comprising SMA+, wherein the water-soluble aqueous phase polymerizate comprises recurring structural units derived from a monomer A2 having the general formula: ##STR12##in which R.sub.8 is H or methyl, Z.sub.2 is 0, NH or NR.sub.10, wherein R.sub.10 is a C.sub.1-6 alkyl or hydroxyalkyl or C.sub.5-12 cycloalkyl radical, R.sub.9 is a C.sub.1-6 alkylene or hydroxyalkylene radical, L.sub.4 and L.sub.5, which may be identical or different, are each a C.sub.1-12 alkyl or hydroxyalkyl or C.sub.5-12 cycloalkyl or C.sub.6-12 aryl radical, and X is an ion.
