ABSTRACT:
Melt-fusible polyimides based on pyromellitic dianhydride and 2,2-bis[3,5-dichloro-4-(4-aminophenoxy)phenyl]propane, alone or in combination with other defined diamines, are useful in making low-void composites and thermoplastic tapes, which can be fabricated into articles such as, for example, aircraft and autobody panels, printed circuit boards, etc.
