WATER-SOLUBLE COPOLYMERS .39. SYNTHESIS AND SOLUTION PROPERTIES OF ASSOCIATIVE ACRYLAMIDO COPOLYMERS WITH PYRENESULFONAMIDE FLUORESCENCE LABELS
Polymers and High Performance Materials
Pyrenesulfonamide-labeled model associative polymers have been prepared via copolymerization of acrylamide with 0.5 mol % N-[(1-pyrenylsulfonamido)ethyl]acrylamide. Synthesis of this monomer and details of copolymerization with acrylamide via surfactant and solution copolymerization techniques are described. The microheterogeneous surfactant technique yields a copolymer which exhibits intermolecular associative behavior in aqueous media as demonstrated by rheological and steady-state fluorescence studies. Conversely, classical light scattering studies indicate the compact nature of the copolymer prepared by the homogeneous solution technique. Intramolecular hydrophobic associations, indicated by a low second virial coefficient and a small hydrodynamic volume, dominate rheological behavior.
