ABSTRACT:
A chemically initiated water-in-oil emulsion polymerization process is disclosed for making water-soluble anionic copolymers from water-soluble, ethylenically unsaturated, addition polymerizable monomers. Improved products are obtained by adding a water-soluble salt to the aqueous phase of the water-in-oil emulsion prior to polymerization.
