20100273949 | Star macromolecules for personal and home care - A polymer composition comprising star macromolecules is provided. Each star macromolecule has a core and five or more arms, wherein the number of arms within a star macromolecule varies across the composition of star molecules. The arms on a star are covalently attached to the core of the star; each arm comprises one or more (co)polymer segments; and at least one arm and/or at least one segment exhibits a different solubility from at least one other arm or one other segment, respectively, in a reference liquid of interest. | 10-28-2010 |
20110112267 | Star macromolecules for personal and home care - A polymer composition comprising star macromolecules is provided. Each star macromolecule has a core and five or more arms, wherein the number of arms within a star macromolecule varies across the composition of star molecules. The arms on a star are covalently attached to the core of the star; each arm comprises one or more (co)polymer segments; and at least one arm and/or at least one segment exhibits a different solubility from at least one other arm or one other segment, respectively, in a reference liquid of interest. | 05-12-2011 |
20110263722 | Well Defined stars with segmented arms - 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. | 10-27-2011 |
20110286935 | Multi-Functional Nano-Device - A universal drug delivery platform for monoclonal antibody-based therapeutics is described. This universal platform resolves the problems of immunogenic response associated with the present monoclonal antibody based therapeutics by providing a multifunctional nano-device which comprises a well defined core/shell nano-structure that can function as a drug delivery platform linked to a monoclonal antibody through a single linking group. | 11-24-2011 |
