Chain-Growth Polymerization of 2-Chlorothiophenes Promoted by Lewis Acids

By Baltasar Bonillo Fernandez and Timothy Manning Swager

Abstract

Lewis acids promote the polymerization of several 2-chloroalkylenedioxythiophenes, providing high-molecular-weight conjugated polymers. The proposed mechanism is a cationic chain-growth polymerization, as confirmed by end-capping reactions and a linear correlation of molecular weight with percent conversion. The “living” character of this process was used to prepare new block copolymers.United States. Air Force Office of Scientific Research (FA9550-10-1-0395
