Ionic liquids (ILs) are widely used as a green solvent both in academics and industry for a wide range of chemical reactions. In the field of polymer chemistry, many cationic and radical polymerizations in ILs have been reported(1). In contrast, anionic polymerizations in ILs have been largely unexplored due to the incompatibility of strong bases with many ILs(2). We have recently discovered that activated aziridine anionic polymerizations(3) are compatible with many ILs. This is due to the relatively low basicity of the propagating anions. Our efforts to understand the impact of ILs on the polymerizations of aziridines will be discussed.
