The Revival of Nitroxide Mediated Polymerization Controlled radical polymerization (CRP) has been one of the most significant breakthroughs in polymer chemistry over the past 20 years. These free radical polymerization processes display outwardly the features of truly “living” polymerizations (narrow molecular weight distribution and active chain ends) without the need for scrupulously clean reagents and air-free transfers. Many variants have been developed; with some such as atom transfer polymerization (ATRP) and reversible addition fragmentation transfer polymerization (RAFT) becoming the most common. Nitroxide mediated polymerization (NMP), despite being one of the first CRP methods developed, has lagged until recently, being revived by alkoxyamine initiators such as BlocBuilder (Arkema). We will present our work with BlocBuilder to synthesize poly(methacrylates), which were not possible with first-generation nitroxides. Specifically, we will describe the application of a low fraction of a co-monomer, 9-(4-vinylbenzyl)-9H-carbazole (VBK), which enables control of a methacrylate, while also imparting electron-donating properties. Characterization of the polymerization process and its application to functional materials (eg. water-soluble fluorescent copolymers) will be highlighted
