The relaxation kinetics of several thiophene/3‐alkylthiophene (3‐methylthiophene and 3‐octylthiophene) random copolymers have been investigated using the cyclic voltammetric method. The first voltammograms, obtained after the polymer films were maintained at potentials corresponding to their neutral state for various periods of time, have been analyzed according to the procedure developed by Odin et al. Considerable suppression of the relaxation kinetics was achieved in copolymers containing thiophene rings substituted with longer alkyl groups (octyl). Copyright © 2004 Society of Chemical Industry
