TITLE WATER-DISPERSIBLE HYDROPHOBIC THICKENING AGENT ABSTRACT OF THE DISCLOSURE An aqueous liquid medium having increased low shear viscosity as provided by dispersing into the aqueous medium (1) a water-soluble polymer having pendant hydrophobic groups, e.g, an acrylamide/dodecyl acrylate/acrylic acid terpolymer. The thickened aqueous medium is suitably employed in applications requiring viscous liquids which retain their viscosity when subjected to shear, heat or high electrolyte (salt) concentrations. Such applications include uses in enhanced oil recovery processes, as fluid mobility control agents, fracturing fluids and drilling muds, as well as hydraulic fluids and lubricants.
