A commercially available tris(3,6-dioxaheptyl)amine (TDA-1) was used as a novel ligand for activator generated by electron transfer atom transfer radical polymerization (AGET ATRP) of styrene in bulk or solution mediated by iron(III) catalyst in the presence of a limited amount of air. FeCl(3)center dot 6H(2)O and (1-bromoethyl)benzene (PEBr) were used as the catalyst and initiator, respectively; and environmentally benign ascorbic acid (VC) was used as the reducing agent. The polymerizations show the features of "living"/controlled free-radical polymerizations and well-defined poly-styrenes with molecular weight M(n) = 2400-36,500 g/mol and narrow polydispersity (M(w)/M(n) = 1.11-1.29) were obtained. The "living" feature of the obtained polymer was further confirmed by a chain-extension experiment. (C) 2009 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 47: 2002-2008, 2009
