Interconvertible Living Radical and Cationic Polymerization Using External Stimuli

Abstract

The development of controlled polymerization such as RAFT polymerization has enabled the synthesis of macromolecules with well-defined structures. Recently, control over polymerization processes has been achieved through regulation of chain growth with various external stimuli. This review highlights the interconversion between living radical and cationic polymerization using external stimuli. Photochemical and electrochemical stimuli are effective to switch the polymerization mechanism and the monomer selectivity in situ.
