The ugly brothers of epoxides: aziridines are typically polymerized by uncontrolled cationic polymerization. Only scarcely anionic ring-opening polymerization (ROP) has been described. The presentation will introduce a whole new monomer class of sulfonamide-activated aziridines that can undergo anionic ROP. In most cases the polymerization mechanism follows a living mechanism and can be combined with other anionic polymerization setups easily. We believe that the anionic ROP of aziridines will provide straightforward access to novel polyamides and –amines with interesting properties for many applications. The presentation will show the progress in the control on sequencing, monomer design, and combination to oxyanionic polymerization.
