  • Aramid compositions of improved solubility and flame retardancy
    Patent number: 5420225
    Abstract: Aramid polymers, e.g., those derived from p-phenylene diamine and terephthaloyl chloride, can have their solubility properties and flame retardancy enhanced by the incorporation therein of a moiety derived from a bis(aminophenoxyphenyl) phosphine oxide, e.g., bis(3-aminophenoxy-4'-phenyl) phenylphosphine oxide.
    Type: Grant
    Filed: July 26, 1991
    Date of Patent: May 30, 1995
    Assignee: Virginia Tech Intellectual Properties, Inc.
    Inventors: Attila Gungor, James E. McGrath, Yadollah Delaviz, Harry W. Gibson
  • Poly(amide-acid) compositions derived from tetracarboxylic acid dianhyrides capable of solution imidization
    Patent number: 5194565
    Abstract: The imidization temperature of poly(amide-acid) compositions derived from tetracarboxylic acid dianhydrides can be lowered by use of a bis(aminophenoxyphenyl) phosphine oxide in the diamine component which is reacted with the dianhydride. These homo- or copolyimides can be cyclized without use of catalysts or excessive temperature which can product undesired side reactions. Tough film forming materials can be produced which show excellent thermo-oxidative stability and high char yields even at 800.degree. C. in air.

    Inventors: James E. McGrath, Attila Gungor
  • Novel phosphorus containing epoxy networks based on trihydrocarbyl phosphine oxides having active substituents
    Patent number: 5086156
    Abstract: Epoxy resins can be cured or crosslinked with trihydrocarbyl phosphine oxide compounds having epoxy-reactive (active hydrogen) substituents either alone or in combination with amine-terminated polyarylene ethers (e.g., amine-terminated polysulfone oligomers or high polymers.
