polybenzimidazoles

https://doi.org/10.1351/goldbook.08888
Polymers composed of macromolecules containing benzimidazole groups in the backbone, such as groups (structure-based polymer class name).
Note:
Polybenzimidazoles are proton-conducting polymers with a high thermal stability that found applications as membranes for example in fuel cells or fibers for flame resistant clothes.
