In 2005, Benicewicz et al. (in cooperation with BASF Fuel Cell GmbH) reported a new method for producing PBI films imbibed with phosphoric acid [8], This process, termed the PPA process, represents a sol-gel process that utilizes PPA as both the polymerization medium and the casting solvent for PBI polymers. In the PPA Process, dicarboxylic acids and tetramines such as 3,3, 4,4 -tetraaminobiphenyl (TAB) (or AB type monomers) are polymerized in PPA between 195 and 220 °C to produce high molecular weight PBI polymers. After polymerization, the PPA solution containing PBI is directly cast mito... [Pg.217]
