A new method, AGET ATRP mediated by an iron(III) catalyst using Fe( 0) powder as a reducing agent and MMA as a model monomer, is reported. The polymerizations can be carried out in the absence or presence of a limited amount of air and show the features of a "living';';/controlled radical polymerization. MMA conversions of 90.3 and 80.0% can be obtained in 3.5 and 4.0 h in the absence/presence of a limited amount of air, respectively, for the iron-mediated AGET ATRP with a molar ratio of [MMA](0)/[EBiB](0)/[FeCl(3) center dot 6H(2)O](0)/[PPh(3)](0)/[Fe(0)](0) = 600: 1:0.5:2:0.1 at 90 degrees C. PMMA with molecular weights of 55 060 and 47 790 g . mol(-1) and with molar-mass dispersity of 1.24 and 1.28, respectively, can be obtained correspondingly.
