Abstract
The stable nitroxide TEMPO is shown to react with styrene and polystyr ene models under conditions typically used for polymerizations. These results show that the nitroxide is not inert at the elevated temperatu res necessary to conduct polymerizations. The implications of hydrogen abstraction and olefin addition by the nitroxide are discussed, parti cularly as they apply to initiation, control of polydispersity and nit roxide mediated autopolymerization of styrene.
