    Abstract: A process for converting 1,4-butanediol to tetrahydrofuran using polybenzimidazole to catalyze the reaction. The conversion is accomplished by heating the 1,4-butanediol in the presence of the PBI. The THF product may be distilled from the reaction solution as an azeotrope with water. To function as the catalyst, the PBI must first be pre-treated with a strong aqueous acid such as sulfuric acid. The catalyst may be in the form of microporous resin beads, hollow fibers, or other forms of PBI. This process exhibits a high selectivity for producing THF without side reactions.

    Abstract: Sintered polybenzimidazole articles are obtained by compacting a particulate, dried polybenzimidazole resin under a pressure of 2,000 to 10,000 psi in a mold, heating the formed article to a temperature in the range of 825.degree. to 950.degree. F. for at least four hours, cooling the polybenzimidazole article to below 800.degree. F. while maintaining the article under a pressure of 2,000 to 10,000 psi, and thereafter heating the constrained formed polybenzimidazole article to a temperature in the range of 825.degree. to 950.degree. F. for at least one hour.

    Abstract: A two stage process for the production of polybenzimidazoles and a novel polybenzimidazole produced there by is provided wherein a mixture of an aromatic tetraamine, e.g., 3,3',4,4'-tetraaminobiphenyl and a free dicarboxylic acid, e.g., isophthalic acid, is heated with agitation in a first stage to a temperature above the melting point of the tetraamine until the viscosity of the mixture rises as indicated by an agitator torque of at least 1.5 times that before the rise in viscosity. The agitation is then discontinued and the reaction mixture is allowed to foam while heating is continued. The foam is then allowed to cool to a friable mass and is crushed to a ground prepolymer which is heated with agitation in a second stage until the desired polymer is obtained. The novel polybenzimidazole produced is the reaction product of phenylindandicarboxylic acid and 3,3',4,4'-tetraaminobiphenyl.
