Tremendous developments on living or "controlled/living" polymerization technique have been achieved over the last couple of decades in polymer chemistry. Now living polymerizations have been developed through various intermediates, such as radical, cationic, anionic, or metal coordination polymerization. However, since chain-growth polymerization of vinyl monomers is implemented via appropriate active species depending on the monomer structure, there are always limitations of polymerizable monomers inherent to the mechanisms. In this work, reversible mechanistic transformation was examined between different active species during controlled/living polymerizations by using dormant covalent bonds, which have been used just for controlling the propagation. Especially, reversible or interconvertible mechanistic transformation of radical species was investigated from or into cationic or anionic species for developing unprecedented copolymers. |
