  • Ethynyl-containing aromatic polyamide resin
    Patent number: 4752642
    Abstract: Aromatic polyamide resins having repeating units, each containing at least one m-ethynyl amido subunit: ##STR1## These resins can be thermally treated to undergo intra-molecular cyclization, without evolution of volatiles, into polyimidines containing the following subunit.
    Type: Grant
    Filed: September 16, 1986
    Date of Patent: June 21, 1988
    Assignee: The United States of America as represented by the Secretary of the Air Force
    Inventors: Robert C. Evers, George J. Moore

    Inventors: Robert C. Evers, George J. Moore
  • Ethynyl-containing phthaloyl halides
    Patent number: 4657708
    Abstract: Aromatic monomers, each containing at least one o-ethynyl carboxylic acid halide subunit: ##STR1## wherein X is Cl or Br. These monomers can be reacted with amines to form aromatic polyamide resins which can be thermally treated to undergo intromolecular cyclization, without evolution of volatiles, into polyimidines.
    Type: Grant

  • 2-Amino-4-ethynylphenol
    Patent number: 4181681
    Abstract: 2-Amino-4-ethynylphenol, a novel compound, is prepared by a four-step synthetic sequence in which the key reaction is the treatment of 4-acetoxy-3-nitroacetophenone with a Vilsmeier reagent derived from N,N-dimethylformamide and phosphorus oxychloride. The compound is useful as an endcapping agent in the synthesis of fluorocarbon ether bibenzoxazole oligomers which, because of the presence of acetylenic terminal groups, can be cured by thermal means to provide broad-use temperature, fuel and fluid resistant vulcanizates.
