This paper reports on the synthesis of conducting polypyrrole and polythiophene grafted block copolymers of methylmethacrylate (MMA) and 3-methylthienylmethacrylate (MTM) by a multi-step process. For this purpose, block copolymers of MMA and MTM were prepared by controlled radical polymerization using 1,1-diphenylethene (DPE). Subsequently, polypyrrole and polythiophene sequences were grafted onto these block copolymers by constant potential electrolysis.
