Poly(1‐substituted pyrrole)s were prepared on a platinum electrode with different electrolysis times, and their properties were studied by cyclic voltammetry. The oxidation potential for most of the poly(1‐alkylpyrrole)s were almost 0.3 V versus the Ag/Ag + reference electrode, except for poly(1‐butylpyrrole). The electron transfer rate in polymer films depends on the electrolysis time and the size of the substituent. The difference of the redox peak potential of poly(1‐phenylpyrrole) was smaller than that of poly(1‐anisylpyrrole) films. The role of a substituent in the electrochemical behavior of the polymer main chain is discussed. © 1998 John Wiley & Sons, Inc. J. Appl. Polym. Sci. 70: 471–475, 1998
