摘要：

Poly[2,2'‐(m‐phenylene)‐5,5'‐bibenzimidazole] (PBI) is shown to be miscible with poly(4‐vinyl pyridine) over the entire composition range. Experiments were performed with commercial PBI as well as a lower molecular weight material synthesized by us. Blend miscibility is evidenced by single glass transition temperature intermediate between the pure polymers. Hydrogen bonding between the components was detected by infrared spectroscopy.
