Poly(p-phenylene) also fascinated many workers due to its cheap cost, good mechanical strength and high stability for use in electrochemical systems. In anodic oxidation and over-oxidation studies in aqueous acidic solutions of different nucleophilicity by cyclic voltammetry, two peaks were observed. The reversible first peak was attributed to poly(p-phenylene) oxidation and formation of some insertion compound, whereas the strong and irreversible second peak at higher potentials was attributed to over-oxidation of the polymer [291] and the polymer anode started degrading at acid concentrations below 13 M [292], Accordingly, the microanalytical, IR spectroscopic and acid-base titration studies showed evidence of the formation of aromatic dicarboxylic acid, phenolic compound and carbondioxide via a p-benzoquinone intermediate [291],... [Pg.853]
