The invention relates to aqueous dispersions of water soluble polymers, formed by polymerization of a mixture A of various monomer components (al, a2, and possibly a3) in the presence of a polymeric dispersant D; wherewith the mixture A is comprised of the following different monomer components: a1 (in the amount of 99-70 wt.%), comprised of at least one water soluble monomer, a2 (in the amount of 1-30 wt.%), comprised of at least one hydrophobic monomer, and (possibly) a3 (in the amount of 0-20 wt.%), comprised of at least one amphipathic monomer, wherewith in each instance the sum of the amounts of a1, a2, and a3 is 100%; and wherewith the water soluble polymers have a mean molecular weight M W (gravimetric mean) of at least 10 6 Dalton. |
