title: A Highly Active Iron-Based Catalyst System for the AGET ATRP of Styrene.
abstract: The atom transfer radical polymerization of styrene using activators generated by electron transfer (AGET ATRP) has been carried out in bulk in a limited amount of air at 110 °C, using 1,3,5-(2'-bromo-2'-methylpropionato)benzene (BMPB) as an initiator and FeCl(3)  · 6H(2) O/tris(3,6-dioxaheptyl) amine (TDA-1)/ascorbic acid (VC) as a novel Fe(III) -mediated catalyst system. The results of the polymerizations demonstrate the features of 'living'/controlled free-radical polymerization, such as the number-average molecular weights being close to their corresponding theoretical values and increasing linearly with monomer conversion, and narrow molecular weight distributions ($\overline M _{\rm w} /\overline M _{\rm n}$ = 1.18-1.26). The end functionality of the obtained polymers was confirmed by (1) H and (13) C NMR spectra as well as a chain-extension reaction.
