Tevenot, Quentin; Kawahara, Seiichi published their research in Langmuir in 2021. The article was titled 《ATRP-ARGET of a Styrene Monomer onto Modified Natural Rubber Latex as an Initiator》.Synthetic Route of Br2Cu The article contains the following contents:
Atom transfer radical polymerization with an activator regenerated by electron transfer (ATRP-ARGET) was performed for graft copolymerization of styrene onto natural rubber in the latex stage as a heterogeneous system. Deproteinized and subsequently brominated natural rubber particles in the latex stage were subjected to graft copolymerization of styrene on their surfaces in the presence of an activated ATRP catalyst. 1H NMR spectroscopy and size exclusion chromatog. (SEC) characterized the particles. Ozonolysis was performed to deduct the polyisoprene contribution to SEC. Graft copolymerization in heterogeneous media by extraction with an acetone/2-butanone solution Both the linear evolution of the mol. weight vs. monomer conversion and the high grafting efficiency associated with a narrow mol. weight distribution of the resulting grafted polystyrene confirm a living radical behavior.Cupric bromide(cas: 7789-45-9Synthetic Route of Br2Cu) was used in this study.
Cupric bromide(cas: 7789-45-9) can be used as reducing agent, when complexed by three molecules of pyridine initiators for the controlled polymerization of styrene, methyl acrylate and methyl methacrylate.Synthetic Route of Br2Cu
