“…66 ) Also, it should be noted that the reduced viscosity decreases as the incorporation of the sulfobetaine moiety increases, again from the intramolecular aggregation brought about by dipole-dipole interactions. 13 This collapse is also observed in light scattering by a decrease in the polymer-solvent interaction parameter, A2, as the mol % sulfobetaine increases (Table 4). The aqueous solution properties of this copolymer series were further evaluated by observing apparent viscosity changes with increasing polymer concentration and ionic strength (Figure 8).…”

“…Polysulfobetaines are typically insoluble in deionized water and require a relatively high content of hydrophilic comonomer or the addition of a critical concentration of electrolyte to achieve solubility and viscosity enhancement. Polysulfobetaines have also been synthesized from acrylic, [5][6][7][8][9][10][11][12] acrylamido, [13][14] and vinyl imidazolium [15][16][17] monomers and more recently polysulfobetaine block copolymers have been reported. [18][19] Another area of interest in our laboratories is the synthesis of hydrophobically modified (HM) water-soluble polymers via micellar copolymerization and their solution behavior in aqueous media.…”

“…No phase separation or precipitation of the polymers occurred during polymerization, indicating that homogeneous polymerization conditions persisted throughout the reaction. Representative inverse gated decoupled 13 C NMR spectra are shown in Figure 4. Peak assignments were confirmed through DEPT135 analysis.…”

“…Since the DiC 12 AM, DiC 14 AM, or DiC 16 AM twin-tailed monomers were not commercially available, we first synthesized the N,N-disubstituted amines and subsequently their corresponding monomers as outlined in the experimental section. Characterization of the hydrophobic monomers was accomplished using 1 H NMR, 13 C NMR and FT-IR. Details are provided in the experimental section.…”

This report contains a series of terpolymers containing acrylic acid, methacrylamide and a twin-tailed hydrophobic monomer that were synthesized using micellar polymerization methods. These polymer systems were characterized using light scattering, viscometry, and fluorescence methods. Viscosity studies indicate that increasing the nonpolar character of the hydrophobic monomer (longer chain length or twin tailed vs. single tailed) results in enhanced viscosity in aqueous solutions. The interactions of these polymers with surfactants were investigated. These surfactants include sodium dodecyl sulfate (SDS), cetyl trimethylammonium bromide (CTAB), Triton X-100. Viscosity measurements of DiC 6 AM and DiC 8 AM mixtures indicate little interaction with SDS, gelation with CTAB, and hemimicelle formation followed by polymer hydrophobe solubilization with Triton X-100. The DiC 10 Am terpolymer shows similar interaction behavior with CTAB and Triton X-100. However, the enhanced hydrophobic nature of the DiC 10 polymer allows complex formation with SDS as confirmed by surface tensiometry. Fluorescence measurements performed on a dansyl labeled DiC 10 Am terpolymer in the presence of increasing amounts of each of the surfactant indicate relative interaction strengths to be CTAB>Triton X-100>SDS.A modified model based on Yamakawa-Fujii and Odjik-Skolnick-Fixman theories was found to describe the contribution of electrostatic forces to the excluded volume of a polyelectrolyte in solution. The model was found to be valid for flexible polymer coils in aqueous salt solutions where intermolecular interactions are minimal. The model suggested that a dimensionless group of parameters termed the dimensionless viscosity should be proportional to the dimensionless ratio of solution screening length to polyion charge spacing. Several sets of experimental data from the literature and from our laboratory have been analyzed according to the model and the results suggest that the two dimensionless groups are indeed related by a universal constant. This model has identified the parameters that are important to fluid mobility, thereby revealing methods to enhance solution performance when using polyions solutions as displacing fluids in oil reservoirs. 5 EXECUTIVE SUMMARYTo date, our synthetic research efforts have been focused on the development of stimuli-responsive water-soluble polymers designed for use in enhanced oil recovery (EOR) applications. These model systems are structurally tailored for potential application as viscosifiers and/or mobility control agents for secondary and tertiary EOR methods. The goal of previous synthetic work has been to design novel polymers that exhibit large dilute solution viscosities in the presence of the adverse conditions normally encountered in oil reservoirs (such as high salt concentrations, the presence of multivalent ions, and elevated temperatures). The polymers are also designed to have "triggerable" properties that can be elicited by external stimuli, such as changes in pH and/or sal...
