ABSTRACT:
Dispersions of finely divided high molecular weight polyacrylamide particles are formed and treated with a caustic material to hydrolyze the polymer without undesirable side chain reactions to form high molecular weight anionic acrylamide polymers. A preferred technique for forming these products comprises the formation of a stabilized water-in-oil emulsion of aqueous acrylamide monomer, polymerizing the monomer, reacting the polymer emulsion thus formed with a hydrolysis agent and inverting the resultant hydrolyzed polymers into solution. These materials are useful in a variety of industrial applications for removing particulates from effluent streams.
