  • Stretchable polymers and shaped articles produced by same
    Patent number: 6294640
    Abstract: A stretchable liquid crystal polymer having recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, at least one aromatic diacid and at least one aromatic diol and/or hydroxyamine component, at least a portion of which is 4,4′-biphenol, and one or more aromatic monomers that provide the polymers with selected 1,3-(meta-) linkages. Stretchable polymers are especially suitable for multilayer laminates and bicomponent fibers.
    Type: Grant
    Filed: August 25, 2000
    Date of Patent: September 25, 2001
    Assignee: Ticona LLC
    Inventors: H. Clay Linstid, III, Dominick L. Cangiano, Ronald N. DeMartino, James E. Kuder, Vincent J. Provino, Randy Jester
  • Process for producing amorphous anisotropic melt-forming polymers having a high degree of stretchability
    Patent number: 6222000
    Abstract: Process for producing highly stretchable, amorphous anisotropic melt-forming polymers having recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, at least one aromatic diacid and at least one aromatic diol and/or hydroxyamine component, at least a portion of which is 4,4′-biphenol, which process comprises incorporating into such polymers recurring units derived from one or more aromatic monomers that provide the polymers with selected meta-linkages wherein each of said recurring units is present in the polymer in specific amounts.
    Type: Grant
    Filed: January 14, 2000
    Date of Patent: April 24, 2001
    Assignee: Ticona LLC
    Inventors: H. Clay Linstid, III, Dominick L. Cangiano, Ronald N. DeMartino, James E. Kuder, Vincent J. Provino
  • Process for producing amorphous anisotrophic melt-forming polymers having a high degree of stretchability and polymers produced by same
    Patent number: 6132884
    Abstract: Process for producing highly stretchable, amorphous anisotropic melt-forming polymers having recurring units derived from p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, at least one aromatic diacid and an aromatic diol and/or hydroxyamine component, at least a portion of which is 4,4'-biphenol, which comprises incorporating into such polymers recurring units derived from resorcinol and at least one additional monomer that provides the resulting polymer with selected meta linkages, wherein each of said recurring units is present in the polymer in specified amounts.
    Type: Grant
    Filed: January 14, 2000
    Date of Patent: October 17, 2000
    Assignee: Ticona LLC

  • Monoanhydride compounds, method of making same and reaction products thereof
    Patent number: 5710241
    Abstract: The present invention relates to monoanhydride monomer compounds, methods of making such compounds and reaction products of the monoanhydride-diacid compounds with other monomers. The inventive monomer compounds exhibit selective reactivity, that is, the dianhydride locus is substantially more reactive towards amines than the diacid locus making it possible to sequentially synthesize a new class of materials suitable for membranes, catalytic substrates or any speciality material required for advanced applications.
    Type: Grant
