Preparation of polybenzimidazole_Kain Industrial Additive

Background and overview[1][2] In the 1920s, people began to study the application of polyvinylbenzimidazole in the fields of rubber, fiber and coatings. In the late 1950s, research began on polybenzimidazole polymers containing benzimidazole groups on the polymer backbone. This type of polymer is mainly produced by the polycondensation reaction of tetraaminoaromatic compounds and dicarboxylic acid…
