Diminishing catalyst concentration in atom transfer radical polymerization with reducing agents
Krzysztof Matyjaszewski,Wojciech Jakubowski,Ke Min,Wei Tang,Jinyu Huang,Wade A. Braunecker,Nicolay V. Tsarevsky +6 more
TL;DR: In this paper, the concept of initiators for continuous activator regeneration (ICAR) in atom transfer radical polymerization (ATRP) is introduced, whereby a constant source of organic free radicals works to regenerate the CuI activator, which is otherwise consumed in termination reactions when used at very low concentrations.
Journal ArticleDOI
Understanding atom transfer radical polymerization: effect of ligand and initiator structures on the equilibrium constants.
Wei Tang,Yungwan Kwak,Wade A. Braunecker,Nicolay V. Tsarevsky,Michelle L. Coote,Krzysztof Matyjaszewski +5 more
TL;DR: Equilibrium constants in Cu-based atom transfer radical polymerization (ATRP) were determined for a wide range of ligands and initiators in acetonitrile at 22 degrees C and excellent correlations of the equilibrium constants with the Cu(II/I) redox potentials and the carbon-halogen bond dissociation energies were observed.
Journal ArticleDOI
Effects of initiator structure on activation rate constants in ATRP
Wei Tang,Krzysztof Matyjaszewski +1 more
TL;DR: In this article, the activation rate constants for a variety of initiators for Cu-mediated ATRP have been determined under the same conditions and the ratio of the studied alkyl (pseudo)halides exceeds 1 million times.
Journal ArticleDOI
Determination of Equilibrium Constants for Atom Transfer Radical Polymerization
TL;DR: Modified Fischer's equations for the persistent radical effect of Atom transfer radical polymerization equilibrium constants (K(ATRP) were determined using modified equations that take into account the changes in catalyst and initiator concentrations by detailed kinetic simulations.
Journal ArticleDOI
Role of Cu0 in Controlled/“Living” Radical Polymerization
Krzysztof Matyjaszewski,Nicolay V. Tsarevsky,Wade A. Braunecker,Hongchen Dong,Jinyu Huang,Wojciech Jakubowski,Yungwan Kwak,Renaud Nicolaÿ,Wei Tang,Jeong Ae Yoon +9 more
TL;DR: In this paper, a single-electron-transfer living radical polymerization (SET-LRP) was proposed to produce alkyl halide radical anion intermediates via outer-sphere electron transfer.
