Abstract
Terpolymers composed of acrylic acid, methacrylamide, and DiC(6), DiC(8), or DiC(10) twin-tailed hydrophobic monomers have been synthesized using micellar polymerization methods, and the interactions of these polymers with surfactants were investigated. These surfactants include sodium dodecyl sulfate (SDS), cetyl trimethylammonium bromide (CTAB), and 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 to 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 surfactants indicate relative interaction strengths to be CTAB > Triton X-100 > SDS.
