High heat copolyimide, articles prepared therefrom, and methods for making copolyimide articles |
| abstract |
A copolyimide comprises a reaction product of an aromatic dianhydride component and an organic diamine component, the aromatic dianhydride component comprising substituted or unsubstituted pyromellitic dianhydride or functional derivatives thereof and aromatic bis(ether phthalic anhydride) or their functional derivatives, and the organic diamine component comprises substituted or unsubstituted phenylenediamines and diaminodiphenylsulfones. Articles and compositions comprising copolyimides and methods of making polyimide films are also described. |
