✦ Synopsis

The stable nitroxide TEMPO is shown to react with styrene and polystyrene models under conditions typically used for polymerizations. These results show that the nitroxide is not inert at the elevated temperatures necessary to conduct polymerizations. The implications of hydrogen abstraction and olef'm addition by the nitroxide are discussed, particularly as they apply to initiation, control of polydispersity and nitroxide mediated autopolymerization of styrene.
