Metal-Free Atom Transfer Radical Polymerization [PDF]
Journal 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 ...

Cellulose Modification Through Grafting of Polyacrylonitrile by Atom Transfer Radical Polymerization [PDF]
علوم و تکنولوژی پلیمر, 2015 In addition to properties such as biocompatibility and biodegradability, cellulosic natural fibers have a higher strength property than the synthetic polymers and glass fibers. So they are suitable alternatives to synthetic and glass fibers.

Metal-free atom transfer radical polymerization with ppm catalyst loading under sunlight
Nature Communications, 2021 Organocatalytic atom transfer radical polymerization (O-ATRP) is attractive due to its metal-free nature but catalysts are rarely applied at a low loading. Here the authors introduce a catalyst design logic based on heteroatom-doping of polycyclic arenes,
