dc.description.abstract	The synthesis of aromatic carboxyl functionalized polymers by atom transfer radical polymerization is described. The α-bromo-p-toluic acid (1) initiated polymerization of styrene in the presence of copper(I) bromide and 2,2′-bipyridyl affords quantitative yields of the corresponding aromatic carboxyl functionalized polystyrene (2). Polymerization proceeded via a controlled free radical process to afford quantitative yields of the corresponding aromatic carboxyl functionalized polymers with predictable molecular weights (Mn = 1600-25900 g mol-1), narrow molecular weight distribution (Mw/Mn = 1.1-1.40) and an initiator efficiency above 0.87. The polymerization process was monitored by gas chromatographic analysis. The functionalized polymers were characterized by thin layer chromatography, size exclusion chromatography, spectroscopy, potentiometry and elemental analysis.	en
