Determination of Rate Constants for the Activation Step in Atom Transfer Radical Polymerization Using the Stopped-Flow Technique
Résumé
The synthesis of macromolecules with well-defined compositions, architectures, and functionalities represents an ongoing effort in the field of polymer chemistry. Over the past few years, atom transfer radical polymerization (ATRP) has emerged as a very powerful and robust technique to meet these goals.1-3 The basic working mechanism of ATRP (Scheme 1) involves a reversible switching between two oxidation states of a transition metal complex.4,5 Typically, copper(I) halide is used in conjunction with a nitrogen-based complexing ligand 4,6-9.
