  • Processes for increasing polymer inherent viscosity
    Patent number: 7683122
    Abstract: Disclosed are processes for preparing polyareneazole polymers including contacting a molar excess of a free base in water with a terephthalic acid salt to form an aqueous mixture, adjusting the pH to precipitate a monomer complex, contacting the monomer complex with metal powder, and polymerizing the monomer complex. Polyareneazoles, filaments and yarns are also disclosed.
    Type: Grant
    Filed: March 27, 2006
    Date of Patent: March 23, 2010
    Assignees: E. I. du Pont de Nemours and Company, Magellan Systems International, LLC
    Inventors: Doetze Jakob Sikkema, David J. Rodini, Qinghong Fu Adkins, Steven R. Allen, Georg Valentin Martin, Ralf Demuth, Michael Schelhaas
  • Processes for preparing high inherent viscosity polyareneazoles using metal powders
    Patent number: 7671171
    Abstract: Disclosed are processes for preparing polyareneazole polymers that include contacting, in polyphosphoric acid, azole-forming monomers and metal powder, the metal powder added in an amount of from about 0.05 to about 0.9 weight percent, based on the total weight of the azole-forming monomers, and reacting the azole-forming monomers to form the polyareneazole polymers. Polyareneazoles, filaments and yarns are also disclosed.
