Abstract

In this work, single electron transfer-living radical polymerization (SET LRP) of methyl methacrylate was successfully carried out using CCl4 as initiator and Fe(0)/ethylenediaminetetraacetic acid (EDTA) as catalyst at 25 °C in dimethyl sulfoxide in the presence of air. In addition, ascorbic acid (VC) was used as reducing agent in the polymerization. Kinetics experiments demonstrated that the SET LRP is a ‘living’ polymerization, for example, the ln([M]0/[M]) versus time is linear and the number-average molecular weight values increases with respect to monomer conversion with narrow polydispersities. The amount of EDTA and VC had a profound effect on the polymerization. The ‘living’ characteristics were further verified by chain extension.
