Controlled radical polymerization in the presence of beta-phosphonylated nitroxide — kinetics, mechanism and macromolecular architectures

Abstract

Using a newly designed N-tert-butyl-1-diethylphosphono-2,2- dimethylpropyl nitroxide (DEPN), controlled radical polymerization of styrene and n-butyl acrylate, could be achieved. The rate constant of reversible deactivation of growing radicals by DEPN and the rate of dissociation of the alkoxyamine formed were determined. Miscellaneous macromolecular architectures, including block copolymers, stars and star block copolymers, were derived by this chemistry.
