초록

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 ...
