Process for a two stage melt polymerization for the production of polybenzimidazole

A process is presented for the production of high molecular weight polybenzimidazole, in two steps. Step one: provide a first reaction vessel and charge it with at least one aromatic hydrocarbon tetraamine, and a heterocyclic ring making up the dicarboxylic component. Heat the reactants under agitat...
