  • Mechanochemical based synthesis of perfluoropyridine monomers for polymerization
    Patent number: 11970449
    Abstract: The present invention relates to a mechanochemical based synthesis of perfluoropyridine monomers, polymers made using such monomers and methods of making and using articles comprising such polymers. Such perfluoropyridine monomers are easily chemically tuned have the strength needed for high temperature applications and the flexibility needed for low temperature applications. In addition, to the aforementioned monomers, a mechanochemical based synthesis for such perfluoropyridine monomers is provided. All of the aforementioned performance application advantages are also found in polymers comprising Applicants' perfluoropyridine monomers.
    Type: Grant
    Filed: May 26, 2023
    Date of Patent: April 30, 2024
    Assignee: United States of America as represented by the Secretary of the Air Force
