Abstract
A storage stable water-in-oil emulsion composition that includes 5% to 99% by weight of a water-in-oil emulsion polymer including a polymer or copolymer containing repeat units from an acrylamide monomer; 0.1% to 10% by weight of one or more inorganic microparticles; 0.5% to 90% by weight of a carrier solvent; and 0 to 90% by weight of a fluidizing agent. The compositions can be used to treat aqueous systems including paper processing, sludge dewatering and for fracturing fluids for subterranean formations.
