A -- Novel Polybenzimidazole (PBI) Derivatives

Polybenzimidazole (PBI) compounds have unique properties that allow them to resist deformation under high temperatures. For this reason PBIs are used in products such as heat resistant clothing, aircraft, and braided packaging. However, the use of PBIs is limited because the current method of synthesis only allows for fabrication of fibers, not films and other structures. The Idaho National Laboratory (INL) has discovered a method that allows for the fabrication of PBI derivatives that can be used to form films and other structures. This allows for use of PBIs in membranes for high temperature applications and other products. The INL has discovered several different N-substituent carboxyl polybenzimidazole derivatives which are much more soluble in organic solvents than the parent polybenzimidazole. A synthetic route was found that gives a modified PBI that is soluble in tetrahydrofuran (THF), methylene chloride, and chloroform. The modified pathway provides a straightforward post-polymerization synthetic modification that can be carried out at room temperature and gives nearly quantitative yields. Analysis has shown that the method provides high yields of PBI derivatives which retain or exceed the beneficial properties of current PBI compounds. In addition, membrane gas testing showed values that are higher than the parent polymer. The INL is soliciting interest from qualified industrial firms interested in commercializing this technology. The INL has a patent pending on the process which may be licensed exclusively or non-exclusively. See U.S. Patent Application No. 10/969,456. The INL invites interested parties to contact us regarding the details of licensing and implementing this technology into an operation. Interested parties should respond on or before June 1st, 2007. For questions regarding the technology, licensing, and working with the INL, please contact Jason Stolworthy. BUSINESS POINT OF CONTACT: Jason C. Stolworthy, J.D., M.S.
