ABSTRACT:
A process for preparing a water-soluble polymer dispersion is herein provided which is characterized by polymerizing from about 10 to 50 mole percent of a monomer having a formula (II); from about 1 to 50 mole percent of N-alkylacrylamide, N, N-dialkylacrylamide or mixtures thereof; having a formula (III) from about 1 to 70 mole percent acrylamide; and optionally up to about 4 mole percent of a monomer having a formula (I) having a benzyl functionality. The polymerization is carried out in the presence of an aqueous solution of a polyvalent anionic salt which contains (1) a water soluble cationic polymer which is insoluble in the aqueous salt solution and (2) a water soluble cationic polymer which is soluble in the aqueous salt solution.
