## Abstract Copolymers of poly(2,5‐benzimidazole) (ABPBI) and poly[2,2′‐(__p__‐phenylene)‐5,5′‐bibenzimidazole] (__p__PBI) were synthesized for use as fuel cell membranes to take advantage of the properties of both constituents. The composition of the copolymers were controlled by changing the feed
