Fund Project: This work was financially supported by the National Natural Science Foundation of China (Nos. 21174096, 21274100 and 21234005), the Specialized Research Fund for the Doctoral Program of Higher Education (No. 20103201110005), the Project of International Cooperation of the Ministry of Science and Technology of China (No. 2011DFA50530), and the project funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions (PAPD).

Atom transfer radical polymerization of styrene (St) and methyl methacrylate (MMA) in bulk and in different solvents using activators generated by electron transfer (AGET ATRP) were investigated in the presence of a limited amount of air using FeCl36H2O as the catalyst, ascorbic acid sodium salt (AsAc-Na) as the reducing agent, and a cheap and commercially available tetrabutylammonium bromide (TBABr) as the ligand. It was found that polymerization in THF resulted in shorter induction period than that in bulk and in toluene for AGET ATRP of St, while referring to AGET ATRP of MMA, polymerization in THF showed three advantages compared with that in bulk and toluene: 1) shortening the induction period, 2) enhancing the polymerization rate and 3) having better controllability. The living features of the obtained polymers were verified by chain end analysis and chain-extension experiments.
