Iron(III)-Mediated AGET ATRP of Methyl Methacrylate in the Absence of Additional Ligand

The atom transfer radical polymerization on the mechanism of activator generation by electron transfer (AGET ATRP) of methyl methacrylate (MMA) in N,N-dimethylformamide (DMF) in the presence of the catalytic systems, namely, CCl4-FeCl3-1-acetyl-2-phenylhydrazine (APH) and CCl4-FeCl3-ascorbic acid (AA) is reported. The living feature of this process was confirmed by obtaining well-defined polymers with controlled molecular weight, narrow molecular weight distribution, and a chain-extension experiment. Both reducing agents, an APH as well as an AA, possess the equal kinetic activitis.
