The electroactive copolymer of poly(acryloyl chloride)(PAC) and polypyrrole(PPy) was synthesized by the electrochemical polymerization using a polymer precursor which contains pyrrole moiety in its side chain. Poly(acryloyl pyrrole)(PAP) was synthesized by the addition polymerization of monomer obtained by the reaction with acryloyl chloride and potassium pyrrole salt and characterized using FT-IR and H-1-NMR spectroscopy. The electrochemical property and morphology of PAC-g-PPy copolymer was investigated comparing with those PAC/PPy composite.
