There are two main polymerization processes for the synthesis of polybenzimidazole resin from high temperature resistant, aromatic heterocyclic polymer with benzimidazole repeating unit in the main chain of macromolecule: one is solution polycondensation process; The second is the melt polycondensation process. Aromatic PBI is a high temperature resistant engineering plastics. It can be used as the separator of fuel cell and the gasket of self-lubricating bearing, or as the resin base of fiber reinforced composite materials. It can also be spun into fireproof and radiation proof clothing. Low molecular polymer can be used as high temperature resistant adhesive and insulation coatings.
