Electroactive macromonomers based on pyrrole and thiophene: a versatile route to conducting block and graft polymers

The synthesis of block and graft copolymers containing insulating and conducting polypyrrole or polythiophene segments via a two-step procedure is described. Synthetic pathways to prepare pyrrole and thiophene functional macromonomers involving conventional and controlled/living polymerizations such as anionic and cationic ring opening, atom transfer radical polymerization are discussed. The use of these macromonomers in subsequent electrochemical and chemical polymerizations, leading to the formation of copolymers, is presented. (C) 2003 Society of Chemical Industry.
