BASF Corp., Florham Park, N.J., is licensing several patents from the University of Alabama, Tuscaloosa, that cover the use of ionic liquids to dissolve and process cellulose from plants. The new technology is believed to hold great promise for the use of cellulose as a chemical feedstock for modifying plastics and fibers. Ionic liquids are said to be attractive as solvents because they are not flammable, do not evaporate, and exhibit high thermal stability. The technology permits blending resins with a cellulose solution to create performance materials, according to Dr. Robin Rogers, the University’s Chemistry Dept. chairman and director of its Center for Green Manufacturing. He says cellulose and PP can be blended to create packaging films with exceptional tear strength.
