ABSTRACT:
The synthesis, preparation and utilization of vesicle-containing viscoelastic monomer fluids mixed with anionic-alkyl containing copolymers are described. These fluid mixtures possess dramatic rheological behavior at very low concentrations as compared to the two individual components or even in comparison with most conventional water soluble polymers. Marked changes in solution properties are exhibited with minor modification in the structure of the copolymers, monomers, vesicle structure and monomer stoichometry.
In addition, the synthesis, preparation and utilization of a novel family of polymerizable vesicles formed via anionic-cationic interactions are described. These structures are formed under very mild agitation conditions and the resulting solutions possess rheological properties substantially different than either of the individual monomers or conventional polymers formed with these unique monomers. Furthermore these vesicles could be useful in a number of encapsulation schemes.
