Abstract

This report contains information which shows that the blend can in fact be fabricated into films and fibers which exhibit miscibility. Due to a lowering of the glass transition, the blend has improved processability over neat PBI (polybenzimidazole). It will also be shown that the blend fibers can be fabricated into molded bars and are suitable for use as a matrix material. However, in the fabrication process there appear to be competing processes of crosslinking, degradation of the Ultem, and phase separation of the PBI and Ultem which make the physical chemistry of the system quite complex.
