    摘要： This invention describes novel hydrophobically associating ter or tetra polymers which can contain sulfonate functionality which are useful as aqueous fluid rheology or flow modifiers. These high molecular weight water soluble polymers contain both water soluble and water insoluble monomers. The water soluble monomers are N, N dimethylacrylamide acrylamide (DMA) and optionally a salt of an ethylenically unsaturated sulfonic acid (s) or N-vinylpyrrolidinone or a metal acrylate and the water insoluble monomer is a higher alkyl acrylamide (R). The process for their preparation relies on solubilizing the water insoluble monomer into an aqueous micellar solution containing one or more surfactants and the water soluble monomers. The surfactants are specifically selected to enable homogeneous dispersion of the hydrophobic monomer(s) in the presence of anionic sulfonate containing monomers. Redox or free radical initiators are used to copolymerize both the water soluble and water insoluble monomers, forming terpolymers of dimethylacrylamide, alkylacrylamides and acrylamide, and optionally an anionic sulfonate or carboxylate monomer. Aqueous solutions of these hydrophobically associating polymers exhibit enhanced viscosification, reduced salt sensitivity and other desirable rheological properties found useful in a variety of applications.

    摘要： A process is described for producing unique and novel sulfonate-containing terpolymers of water soluble monomers with water insoluble monomers which are efficient viscosifiers of aqueous and brine media. The process relies on the complete solubilization of the water insoluble monomer by means of a dilute solution of a suitable water soluble surfactant. The type and concentration of surfactant are chosen to produce a clear, uniform, homogeneous aqueous dispersion of the hydrophobic monomers in the presence of both nonionic and anionic water soluble monomers, and, in addition, the reaction medium remains a clear, uniform, homogeneous mixture with no phase separation as the reaction proceeds to completion. Thus, the terpolymerization is effected without the formation of latexes or fine particulates of water insoluble polymer.The terpolymers, which may be isolated from the reaction mixture, provide efficient viscosification of water or brine solutions. The anionic sulfonate groups improve polymer solubility in water and brine, particularly in the presence of salts containing divalent cations, and impart some chain stiffness due to charge repulsion, particularly in water containing low electrolyte concentration. The hydrophobic N-alkylacrylamide groups associate in solution to create a structure with an apparent increase in molecular weight, resulting in enhanced thickening efficiency.
