Metal-Free Atom Transfer Radical Polymerization [PDF]

open access: yesJournal of the American Chemical Society, 2014
Overcoming the challenge of metal contamination in traditional ATRP systems, a metal-free ATRP process, mediated by light and catalyzed by an organic-based photoredox catalyst, is reported. Polymerization of vinyl monomers are efficiently activated and deactivated with light leading to excellent control over the molecular weight, polydispersity, and ...
