U.S. Air Force research program began toward the end of his first career at the University of Illinois and continued throughout his entire second career at the University of Arizona. During a 30-year period he was the principal contributor to the Air Force program on high temperature polymer synthesis. His basic research led to the commercialization of polybenzimidazole (PBI)...

Polybenzimidazole (PBI) is the most well-known commercial example of aromatic heterocycles used as high-temperature polymers. The synthesis of PBI is carried out as follows (see also Figure 1.36). The tetraaminobiphenyl required for the synthesis of PBI is obtained from 3,3 -dichloro-4,4 -diaminodi-phenyl (a dye intermediate) and ammonia. Many other tetraamines and dicarboxylic acids have been...

High temperature polymer electrolyte membrane fuel cells (HT-PEMFC) operate in a temperature range of 160 to 180 °C. For the HT-PEMFC the hydraulic system of a house is at any time a heat sink. HT-PEMFC based fuel cells can be used in hydraulic systems of new and existing buildings. Furthermore, the HT-PEMFC requires less effort to cleanup the synthesis gas of the fuel processor. But the HT-PEMFC is only demonstrated in few applications so far and the development status is not so advanced as for the LT PEMFC.

Much of the work that has been done up to this point on high temperature polymer blends is the definition of miscible blend polymer pairs and an understanding of the features that lead to that miscibility. The development of miscible blends often leads to the ability to tailor the properties, including the Tg of mixtures. Such a tailoring is an alternative to the development of entirely new polymeric materials with the desired property profile. One of the advantages of the blend approach is that it is generally faster and less expensive than the synthesis and scale-up of an entirely new polymer. The downside of the blend approach is that it is difficult to define miscible pairs and miscibility is often the situation that is not observed with polymer mixtures.
