摘要

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.
