The free radical polymerization mediated by stable nitroxyl radicals such as 2, 2, 6, 6-tetramethylpiperidinyl-1-oxy (TEMPO) and its derivatives has aroused much interest as a novel and simple synthetic route to welldefined polymers. 1-11 The key process of this method is the reversible dissociation-combination reaction of the alkyl-nitroxyl adduct (Scheme 1a). 3, 12 In hopes of comprehensively understanding and evaluating this new branch of “living” polymerization, we have been studying for some time the mechanism and kinetics of TEMPO …
