  • Microemulsion polymerization systems for the production of small melt-processible fluoropolymer particles
    Patent number: 6037399
    Abstract: An aqueous microemulsion polymerization procedure is described in which very small colloidal melt-processible fluoropolymer particles are produced from at least one gaseous monomer and optionally TFE. The polymerization procedure involves forming a microemulsion of at least one liquid organic compound; adding at least one gaseous free-radical polymerizable monomer to the microemulsion; and initiating polymerization by adding a free-radical initiator to the mixture.
    Type: Grant
    Filed: June 28, 1996
    Date of Patent: March 14, 2000
    Assignee: W. L. Gore & Associates, Inc.
    Inventors: Huey Shen Wu, Jack Hegenbarth, Chen Xin-Kang, Chen Jian-Guo
  • Microemulsion polymerization systems for the production of small polytetrafluorethylene polymer particles
    Patent number: 5880213
    Abstract: An aqueous microemulsion polymerization procedure is described in which very small colloidal polymer particles are produced from tetrafluoroethylene monomer. The polymerization procedure involves forming a microemulsion of at least one liquid saturated organic compound; adding gaseous tetrafluoroalkyl monomer to the microemulsion; and initiating polymerization by adding a free-radical initiator to the mixture.
