ABSTRACT:
This invention discloses a unique process for the preparation of N-substituted polybenzimidazole polymers from unsubstituted polybenzimidazole polymers. An unsubstituted polybenzimidazole polymer is first reacted with an alkali hydride to produce a polybenzimidazole anion which is then reacted with a substituted or an unsubstituted alkyl, aryl or alkenyl methyl halide to produce an N-substituted alkyl, alkenyl or aryl polybenzimidazole polymer. The substituted polybenzimidazole polymer produced by this process can be formed into a wide range of products, such as membranes, films, resins or fibers. The product can be designed to meet special applications by the choice of the substituent. These substituted polybenzimidazole polymers can be utilized for numerous applications including reverse osmosis, ultrafiltration, microfiltration, electrodialysis, ion exchange and affinity chromatography.
