N2  - The kinetics of the electrochemical degradation of polypyrrole has been investigated in aqueous solutions, containing HNO3 or NaNO3. For HNO3 solution, it has been found that the first-order degradation rate constant (k)is ca. 10-5 s-1 within the electrode potential limits of 0.3 to 0.6 V vs. Ag/AgCl. Over 0.6 V, a steep increase of k with increasing electrode potential was found, reaching ca. 9.8 V-1 for logk. For NaNO3 solutions, the k value ranges from 2.8·10-5 to 3.4·10-3 s-1 within the electrode potential limits of 0.3 to 0.9 V, and a linear slope of logk vs. E of 5.1 V-1 was found within the E limits of 0.4 to 0.9 V
