The stringent control over the polymerization of less activated monomers remains one major challenge for Reversible Deactivation Radical Polymerizations (RDRP), including Atom Transfer Radical Polymerization (ATRP). Electrochem. mediated ATRP (eATRP) of a gaseous monomer, vinyl chloride (VC), was successfully achieved for the first time using a stainless-steel 304 (SS304) electrochem. reactor equipped with a simplified electrochem. setup. Controlled polymerizations were confirmed by the good agreement between theor. and measured mol. weights, as well as the relatively narrow mol. weight distributions. Preservation of chain-end fidelity was verified by chain extension experiments, yielding poly(vinyl chloride) (PVC) homopolymers, block and statistical copolymers. The possibility of synthesizing PVC by eATRP is a promising alternative to afford cleaner (co)polymers, with low catalyst concentration The metal body of the reactor was also successfully used as a cathode. The setup proposed in this contribution opens an avenue for the polymerization of other gaseous monomers. In the experiment, the researchers used many compounds, for example, Cupric bromide(cas: 7789-45-9COA of Formula: Br2Cu)
Some reported applications of Cupric bromide(cas: 7789-45-9) are: catalyst in cross coupling reactions; co-catalyst in Sonogashira coupling; lewis acid in enantioselective addition of alkynes.COA of Formula: Br2Cu
