摘要：
A polybenzimidazole (PBI) resin including a polybenzimidazole oligomer having at least two reactive end groups is provided. Also provided is a method of making a polybenzimidazole oligomer with at least two reactive end groups including the steps of reacting a tetraamine, a dicarboxylic component, and a reactive end group moiety in a solvent at a temperature greater than room temperature for a period of time; precipitating the oligomer from the solvent after reacting; and removing any reaction by products from the oligomer after precipitating. A method of making a PBI molded article and a PBI molded article are also provided.
