Living/Controlled Radical Polymerization of Styrene Mediated by Nitroso Compound: Kinetic and ESR Studies

Abstract

The radical polymerization of styrene in the presence of the nitroso-tert-octane have been studied at 90 and 110 °C. From kinetic and ESR experiments it has been established that the process presents the criteria of a living/controlled radical polymerization up to 50% monomer conversion. This has been explained by the initial formation of a nitroxide by addition of a styryl radical on the nitroso compound.
