摘要： 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 copolymer, and (2) a water-dispersible surfactant, e.g., sodium oleate, or dodecyl polyethyleneoxy glycol monoether. The thickened aqueous medium is suitably emloyed 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 in many applications.

摘要： The invention comprises a thickening agent comprising an aqueous-soluble polymerization product of one or more water-soluble monomers which are sufficiently water-soluble to form at least a 10 weight percent solution when dissolved in water and which undergo addition polymerization to form polymers which are water-soluble; and at least one second monomer of the formula:
wherein R is a hydrocarbyl radical which contributes hydrophobic character to the second monomer, Z is a divalent linking group, M is a divalent hydrocarbyl or substituted hydrocarbyl radical and Y is an ionic species which contributes hydrophilic character to the molecule.
These compositions are useful for thickening aqueous mediums, in particular, for thickening equeous media containing water-soluble electrolytes. Such thickened aqueous media retain their viscosity when subjected to shear, heat or high electrolyte concentrations. The thickened aqueous solutions may be used in enhanced oil recovery processes as fluid mobility control agents, fracturing fluids and drilling muds, as well as hydraulic fluids and lubricants.摘要翻译： 本发明包括一种增稠剂，其包括一种或多种水溶性单体的wässrige水溶性聚合产物具有足够的水溶性，以形成至少有10％（重量）溶液时溶于水并进行加成聚合，以形成为聚合物 微溶于水; 和下式的至少一种第二单体：
