  • Siloxane-containing polyimide coatings for electronic devices
    Patent number: 4656235
    Abstract: Siloxane-containing polyimides, useful as conformal coatings for electrical devices, can be synthesized via a novel Diels-Alder reaction in which bis-maleimide derivatives are polymerized with siloxane-containing bis-furan derivatives. The Diels-Alder adduct can be aromatized, and applied as a coating to a mineral substrate. The aromatized, polyimide coating can be cured thermally without additional cyclization on the substrate.
