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. The products obtained by adding NaCl, NaBr, LiCl or LiBr to the aqueous phase of the water-in-oil emulsion prior to polymerization are of increased molecular weight. The addition of such salts also leads to faster rates of polymerization and high conversions of monomer, to polymer. The examples are directed towards the copolymerization of sodium acrylate with acrylamide.
