Poly‐2,2′‐( m ‐phenylene)‐5,5′‐bisbenzimidazole has been alkylated with propanesultone to yield polymers which are readily dyed with basic dyes. Propanesultone has been used to convert cellulose, starch, phenolformaldehyde resin, and various vinyl copolymers into hydrophilic materials which dye readily or act as ion exchange resins. 1–5 It seemed likely it would react with a polybenzimidazole to make the polymer more water absorptive and readily dyeable with basic dyes. Hence this work was undertaken.
