- Advanced polymer systems that possess microstructural features that are responsive to temperature, electrolyte concentration, and shear conditions are being synthesized which will be superior to polymers presently used for mobility control in enhanced oil recovery. Improved polymer performance is accomplished by controlling hydrophobic or ampholytic interations between individual polymer chains in solution. The advanced polymers will circumbent major problems inherent in conventional EOR polymers in which molecular weight is usually compromised to allow sufficient solution viscosity and uniform reservoir permeation without plugging the porous media. Accomplishments are reported for the following tasks: quaternary ammonium cyclopolymer synthesis; characterization of molecular structure and solution behavior; ²³Na NMR studies of non-binding to anionic polyelectrolytes and solution rheology.
