    Abstract: Polymerization processes of the present invention comprise low catalyst concentration. Embodiments include a polymerization process comprising polymerizing free radically (co)polymerizable monomers in a polymerization medium comprising one or more radically (co)polymerizable monomers, a transition metal catalyst complex capable of participating in a one electron redox reaction with an ATRP initiator; a free radical initiator; and an ATRP initiator; (wherein the concentration of transition metal catalyst complex in the polymerization medium is less than 100 ppm). Further embodiments include a polymerization process, comprising polymerizing one or more radically (co)polymerizable monomers in the presence of at least one transition metal catalyst complex; and an ATRP initiator; and a reducing agent; wherein the transition metal catalyst complex is present at less than 10″3 mole compared to the moles of radically transferable atoms or groups present on the ATRP initiator.

    Abstract: Embodiments of the polymerization process of the present invention are directed to polymerizing free radically polymerizable monomers in the presence of a polymerization medium initially comprising at least one transition metal catalyst and an atom transfer radical polymerization initiator. The polymerization medium may additionally comprise a reducing agent. The reducing agent may be added initially or during the polymerization process in a continuous or intermittent manner. The polymerization process may further comprises reacting the reducing agent with at least one of the transition metal catalyst in an oxidized state and a compound comprising a radically transferable atom or group to form a compound that does not participate significantly in control of the polymerization process. Embodiments of the present invention comprise reacting a reducing agent with at least one of catalyst in an oxidized state and a compound comprising a radically transferable atom or group to initiate and/or maintain catalytic activity throughout the polymerization process.

    Abstract: 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.
