Controlled radical polymerization in the presence of b-phosphonylated nitroxide

- kinetics, mechanism and macromolecular architectures (in English)

Polimery 2003, No 7-8, 499


Summary

Using a newly designed N-tert-butyl-l-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.


Keywords: controlled radical polymerization, N-tert-butyl-1-diethylphosphono-2,2-dimethylpropyl nitroxide, styrene, n-butyl acrylate, block copolymers, star polymers
