  • Methods of preparing polyimides and artifacts composed thereof
    Patent number: 4439381
    Abstract: Methods of converting essentially unpolymerized precursors into polyimides in which the precursors are exposed to microwave radiation. Preheating, thermal post-curing, and other techniques may be employed to promote the development of optimum properties; and reinforcements can be employed to impart strength and rigidity to the final product. Also disclosed are processes for making various composite artifacts in which non-polymeric precursors are converted to polyimides by using the techniques described above.
    Type: Grant
    Filed: May 11, 1981
    Date of Patent: March 27, 1984
    Assignee: I M L Corporation
    Inventors: John Gagliani, Raymond Lee, Anthony L. Wilcoxson
