ABSTRACT:
A stable water-in-oil emulsion of a hydrophobe associative copolymer of a water-soluble monomer such as acrylamide and a hydrophobic monomer such as dodecyl methacrylate is formed by subjecting a water-in-oil emulsion of the corresponding monomers to copolymerization conditions in the presence of an oil-soluble initiator such as cumene hydroperoxide. Such copolymers associate in aqueous media containing salts such as sodium chloride to increase the viscosity of such media.
