  • Oligomeric hydroxy arylether phthalonitiles and synthesis thereof
    Patent number: 7511113
    Abstract: An aromatic ether oligomer or polyaromatic ether comprising the formula: O—Arn; wherein Ar is an independently selected divalent aromatic radical; formed by reacting a dihydroxyaromatic with a dihaloaromatic; and wherein the reaction is performed in the presence of a copper compound and cesium carbonate. The polyaromatic ether is formed when neither the dihydroxyaromatic nor the dihaloaromatic is present in an excess amount. The aromatic ether oligomer is formed by using an excess of either dihydroxyaromatic or dihaloaromatic. A phthalonitrile monomer comprising the formula: formed by reacting a 3- or 4-nitrophthalonitrile with a hydroxy-terminated aromatic ether oligomer. A thermoset formed by curing the phthalonitrile monomer. Processes for forming all the above.
    Type: Grant
    Filed: March 17, 2004
    Date of Patent: March 31, 2009
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Teddy M. Keller, Dawn D. Dominguez
