摘要： Random, melt-processible copolyimides are disclosed herein. These copolyimides are semicrystalline and exhibit recoverable (semi)crystallinity from their melts. Associated processes, which entail either solution polymerization or melt polymerization, for producing and fabricating these copolyimides into useful articles having a predetermined shape are also disclosed.

摘要： The assemblies of the present invention comprise an electrode, an absorber layer and a polyimide film. The polyimide film contains from about 40 to about 95 weight percent of a polyimide derived from: i. at least one aromatic dianhydride, at least about 85 mole percent of such aromatic dianhydride being a rigid rod type dianhydride, and ii. at least one aromatic diamine, at least about 85 mole percent of such aromatic diamine being a rigid rod type diamine. The polyimide films of the present disclosure further comprise a filler that: i. is less than about 800 nanometers in at least one dimension; ii. has an aspect ratio greater than about 3:1 ; iii. is less than the thickness of the polyimide film in all dimensions; and iv. is present in an amount from about 5 to about 60 weight percent of the total weight of the polyimide film.
