Poly( o ‐phenylenediamine‐co‐2‐aminobenzothiazole), P( o PD‐co‐2ABT), 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 E [Na 2 SO 4 ] 0.48 [HCl] 1.09 [M] 2.08 . The apparent activation energy ( E a ) is found to be 57.44 kJ mol −1 . The polymer films obtained have been characterized by cyclic voltammetry, X‐ray diffraction, elemental analysis, TGA, scanning electron microscopy, and IR‐spectroscopy. The mechanism of the electrochemical polymerization reaction has been discussed. The monomer reactivity ratios ( r 1 and r 2 ) were calculated using Fineman‐Röss method. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
