摘要: A new Atom Transfer Radical Polymerization (ATRP) process with triphenylphosphine (PPh3) and [CuIIMe6TREN]2+ as the catalyst system is reported. It shown that PPh3 can act not only an efficient reducing agent (RA) but also a supplemental activator (SA). The kinetics mechanism of SARA ATRP methyl acrylate (MA) in DMSO DMSO/H2O (90/10 v/v) were investigated detail. polymers presented controlled molecular weight, very low dispersity (Đ ≈ 1.03), well-defined chain-end functionality. UV-Vis electrochemical studies performed to understand role CuIIBr2/Me6TREN complex MA polymerization. demonstrated presence does affect stability [BrCuIIMe6TREN]+ deactivator. reported results reveal high versatility ATRP, which, besides being commonly used iron-mediated polymerizations, be employed copper-based systems.
