WELL DEFINED STARS WITH SEGMENTED ARMS

摘要

The present invention relates to the preparation and use of well defined star macromolecules wherein the composition of the arms are selected to induce self assembly when the multi-arm segmented star macromolecules are dispersed in a liquid. The self assembled star macromolecules modify the rheology of the dispersing media. When targeting use in aqueous based systems the inner shell of the star macromolecules comprise non-ionizable monomer units. Compositions comprising the self assemblable star macromolecules are suitable for use as rheology modifiers in a number of applications including cosmetic and personal care compositions.
