Polymerization in the presence of a beta-substituted nitroxide radical

Abstract

The invention relates to a process for the polymerization or copolymerization of at least one radically polymerizable monomer in the presence of a stable free radical of the nitroxide family. The stable free radical is β-substituted and provides excellent control of the polydispersity while ensuring a better rate of polymerization or copolymerization, when compared with the stable free radicals implemented by the prior art.
