Atom Transfer Radical Polymerization. Here we demonstrate a rapid and quantitative method to tailor đ of both homo and block copolymers in aqueous atom transfer radical polymerization. An electrochemical variant of organocatalyzed atom transfer radical polymerization o atrp is developed and investigated.
Si atrp is a robust and versatile method for preparation of various hybrid materials with controlled molecular characteristics of the tethered polymer chains such as polymer composition and architecture. Like its counterpart atra or atom transfer radical addition atrp is a means of forming a carbon carbon bond with a transition metal catalyst. Conversely arget and sara atrp are controlled by chemical reducing agents.
The first well controlled aqueous atom transfer radical polymerization atrp conducted in the open air is reported.
The hnts were first ultrasonically dispersed in deionized di water before trishcl 10 mm and dopamine hydrochloride 2 mg ml 1 were added. This air tolerant atrp was enabled by the continuous conversion of oxygen to carbon dioxide catalyzed by glucose oxidase gox in the presence of glucose and sodium pyruvate as sequential sacrificial substrates. First a small introd. Spatial and temporal regulations of atrp by external stimuli are presented.
