Imidazoline Nitroxide‐Mediated Radical Polymerization of Styrene

Nitroxide‐mediated radical bulk polymerizations of styrene were successfully performed using imidazoline nitroxide as mediator. The polymerizations proceeded in a controlled manner. The obtained polymers showed an increase in molecular weight with conversion and narrow molecular weight distributions. The structure of the imidazoline nitroxide, molar ratio of [styrene]0/[BPO]0/[nitroxide]0, and the temperature had a considerable effect on the polymerization. The 1H‐NMR was used to characterize the obtained polystyrene. The living nature of the polymer was confirmed by successful chain extension reaction of the resulting polystyrene.
