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 form new polyamic acids. acids can be imidized a class of useful polyimide resins films, particularly in electronics type applications.
