ABSTRACT:
Water-in-oil emulsions of water-soluble cationic polymers, e.g., a copolymer of acrylamide and acryloylethyl trimethyl ammonium chloride, exhibiting improved emulsion stability are prepared by incorporating a water-soluble salt of a monovalent anion, e.g., ammonium chloride, into the aqueous phase at some point prior to polymerization.
