  • Melt-fusible polyimides
    Patent number: 4576857
    Abstract: Melt-fusible polyimides based on pyromellitic dianhydride and at least one defined aromatic diamine are useful in making low-void composites and thermoplastic tapes, which can be fabricated into articles such as, for example, aircraft and autobody panels, printed circuit boards, etc. Some of these polyimides are melt-processible and can be fabricated by conventional procedures such as extrusion and injection molding.
    Type: Grant
    Filed: September 21, 1983
    Date of Patent: March 18, 1986
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Thomas P. Gannett, Hugh H. Gibbs
