  • Patent number: 7064151
    Abstract: The invention provides in one aspect a process for preparing a microgel by RAFT polymerizing in the presence of a RAFT chain transfer agent, one or more solvophobic monomers and one or more solvophilic monomers to form one or more block copolymers comprising one or more solvophobic blocks and one or more solvophilic blocks wherein the solvophobic block is insoluble in a dispersing medium and the solvophilic block is soluble in the dispersing medium. The block copolymer is dispersed in the dispersing medium to form micelles, which is then stabilized to form the microgel. The dispersing medium can be aqueous or lipophilic. The method of the present invention also permits one to encapsulate a wide variety of materials, such as pigments, dye molecules, and aluminum flakes used in metallized paints.

  • Patent number: 6822056
    Abstract: A process for preparing microgel(s) that uses a wide range of activatable prepolymers; in the process, a polymer composition of crosslinked component A and soluble components B and C is formed from mono-olefinic and multi-olefinic monomers in the presence of catalyst and initiator; the process comprises: I) introducing mono-olefinic monomer, catalyst, and initiator into a reactor in the absence of multi-olefinic monomer and producing an activatable prepolymer, component B; II) contacting the product of I) with multi-olefinic monomer to produce components A and C, optionally in the presence of additional initiator; also optionally in the presence of additional mono-olefinic monomer and initiator; the ratio of components A/(B+C) can be controlled by varying the mole ratio of Component B/multi-olefinic monomer from 0.05/1 up to 5/1, by decreasing the mole ratio to increase the ratio of A/(B+C), and increasing the mole ratio to decrease the ratio of A/(B+C).

  • Patent number: 6653407
    Abstract: The present invention is directed to a process for forming star shaped microgels which include a core of crosslinked polymer and multiplicity of substantially linear polymeric arms of macromonomers attached to the core. The process includes polymerizing monoethylenically unsaturated monomers in the presence of a chain transfer agent to form macromonomers each having a terminal polymerizable ethylenically unsaturated group and then polymerizing, in presence of the macromonomers, the monoethylenically unsaturated monomers and multi-olefinic crosslinking monomers. The microgels of the present invention can be used as rheology control agents in waterborne and solvent-borne coatings and in adhesives and cosmetics.

  • Patent number: 6646070
    Abstract: This invention provides for an aqueous metallic flake containing coating composition having improved glamour. The coating composition includes a neutralized phosphated segmented copolymer dispersed in an aqueous carrier. The phosphorous moiety in the segmented copolymer passivates the metallic flakes, such as aluminum flakes, used to produce the glamour. As a result, generation of hydrogen gas is substantially reduced. The segmented copolymer is provided with hydrophobic and nonionic hydrophilic segments. Applicants have discovered that by including a nonionic hydrophilic segment in the segmented copolymer, glamour of the resultant coating composition can be improved.

  • Patent number: 6646055
    Abstract: A process for preparing microgel(s) that uses a wide range of activatable prepolymers. In the process, a polymer composition of crosslinked component A and soluble components B and C is formed from mono-olefinic and multi-olefinic monomers in the presence of catalyst and initiator. The process comprises: I) introducing mono-olefinic monomer, catalyst, and initiator into a reactor in the absence of multi-olefinic monomer and producing an activatable prepolymer, component B; II) contacting the product of I) with multi-olefinic monomer to produce components A and C, optionally in the presence of additional initiator; also optionally in the presence of additional mono-olefinic monomer and initiator. The ratio of components A/(B+C) can be controlled by varying the mole ratio of The Component B/multi-olefinic monomer from 0.05/1 up to 5/1, by decreasing the mole ratio to increase the ratio of A/(B+C), and increasing the mole ratio to decrease the ratio of A/(B+C).
