Polycyclic polyimides and compositions and methods relating thereto |
摘要 |
The present invention is directed to the use polycyclic diamines. These diamines, when polymerized with dianhydrides, and optionally other non-polycyclic diamines are used to form new polyamic acids. The polyamic acids can be imidized to form a new class of useful polyimide resins and polyimide films, particularly in electronics type applications.
