Abstract
The present invention relates to multi-arm surfactant-system thickening star macromolecules, and methods of preparing and using the same. In one aspect of the invention, a surfactant-system thickening star macromolecule is capable of providing surfactant-compatibility, increase the viscosity of a surfactant-containing system, and/or temperature-stability to an aqueous composition.
