As a result of PBI's reactivity, the molecular interactions between PBI (polybenzimidazole) and polyarylate (PA) polymers have been discovered. The authors present information regarding the assessment of PBI/PA compatibility, the preparation/characterizations of solution and film blends as well as the development of PBI/PA fibers. The compatibility between PBI and PA polymers was first noticed from the solution blends. All PBI/PA solutions were visually homogeneous and contained no insolubles. The inherent viscosity (IV) of all solution blends exhibited normal polymer solution characteristics since the IV and concentration correlations of all solutions were close to linear with small negative slopes. These blends exhibited synergistic effects on properties and offered new opportunities in the development of polymeric alloys for engineering and aerospace applications.
