A water-in-oil emulsion composition and method of production is disclosed. The composition may comprise a monomer phase, an organic phase, at least one initiator, and an inverting phase. The monomer phase may further comprise at least one monomer, water, ammonium chloride, sodium 2-acrylamido-2-methyl-1-propanesulfonate, tetrasodium ethylenediaminetetraacetate, and at least one water soluble ethylenically unsaturated monomer. The organic phase may further comprise at least one hydrophobic solvent, lecithin, and a polyoxyethylene derivative of a sorbitan ...
1. A method of producing a water-in-oil polymer dispersion composition, the method comprising: forming an aqueous monomer inverse emulsion by emulsifying an aqueous monomer solution comprising water, at least one water soluble ethylenically unsaturated monomer and an organic salt in an organic phase comprising a fatty ester, a polyoxyethylene derivative of a sorbitan ester and lecithin, the aqueous monomer inverse emulsion further comprising at least one initiator;forming a water-in-oil polymer dispersion by polymerizing the at least one water soluble et...
