Industrial application of living radical polymerizations will be difficult to realize if the system cannot overcome the obstacle of air-sensitivity of the lower-oxidation-state metals.we report here a new initiation procedure for ATRP, in situ generation of activators via monomer addition for atom transfer radical polymerization (GAMA ATRP), which uses monomer to reduce the initially added high-oxidation-state metal, followed by subsequent in situ generation a new initiator to initiate polymerization. In this study, GAMA ATRP has been successfully extended its applicability as a new ATRP to form well-defined polymers with low polydispersities with a variety of monomers, metal compounds including hygroscopic metal compounds, and ligands. By applying the new redox process to a variety of systems, GAMA ATRP can employ an easier and more convenient experiment condition with hygroscopic metal usage and in the absence of even ATRP initiators. |
