Poly (pyrrol‐ co ‐ o ‐aminobenzoic acid) has been synthesized electrochemically from an aqueous acid medium. The initial rate of electrocopolymerization reaction on platinum electrode is small and the rate law is: Rate = K 2 [D] 1.02 [HCl] 1.44 [M] 2.00 . The apparent activation energy ( E a ) is found to be 90.11 kJ mol −1 . The polymer films obtained have been characterized by cyclic voltammetry, X‐ray diffraction, elemental analysis, thermogravimetric analysis, scanning electron microscopy, 1 H NMR, and IR‐spectroscopy. The mechanism of the electrochemical polymerization reaction has been discussed. The monomer reactivity ratios ( r 1 and r 2 ) were calculated. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
