  • Patent number: 6525106
    Abstract: This application relates to flexible, microporous, open-celled polymeric foam materials with physical characteristics that make them suitable for a variety of uses. This application particularly relates to methods particularly suitable for continuously curing high internal phase emulsions to form such foams.
    Type: Grant
    Filed: August 7, 2001
    Date of Patent: February 25, 2003
    Assignee: The Procter & Gamble Company
    Inventors: Thomas Allen DesMarais, Thomas Michael Shiveley, John Collins Dyer, Stephen Thomas Dick, Bryn Hird
  • Patent number: 6369121
    Abstract: A method of making high internal phase emulsions is described. The method forms high internal phase emulsion (HIPE) using a single pass through the static mixer. In alternative embodiments, the HIPE may be further processed to farther modify the size of dispersed phase droplets, to incorporate additional materials into the HIPE, to alter emulsion temperature, and the like.
    Type: Grant

    Inventors: Vincenzo Catalfamo, Thomas Michael Shiveley, Gina Lynn Blum, Paul Martin Lipic, Thomas Allen DesMarais
  • Patent number: 6362244
    Abstract: This application relates to flexible, microporous, open-celled polymeric foam materials with physical characteristics that make them suitble for a variety of uses. This application particularly relates to degassing the components of the high internal phase emulsions which are subsequently cured to form such foams.

  • Patent number: 5869171
    Abstract: The present invention relates to a HIPE-derived heterogeneous polymeric foam structure of interconnected open-cells, wherein the foam structure has at least two distinct regions. Such heterogeneous foams have various applications, such as energy and fluid absorption, insulation, and filtration.The invention further relates to a heterogeneous absorbent polymeric foam that, upon contact with aqueous fluids (in particular body fluids such as urine and blood), can acquire, distribute, and store these fluids.The foams of the invention have at least two distinct regions having different density, polymer composition, surface properties, and/or microcellular morphology.The invention further relates to a process for obtaining the heterogeneous foams by polymerizing a high internal phase water-in-oil emulsion, or HIPE. In one aspect, the process utilizes at least two distinct HIPEs, with each emulsion having a relatively small amount of an oil phase and a relatively greater amount of a water phase.
