Abstract This presentation will describe a new class of curing resins based on three-membered N-heterocycle, aziridine. Increased complexities in applications involving curable polymers virtually need new materials that can overcome the limitations of existing ones. A series of curing resins, the structure of which is based on three membered N-heterocycle—aziridine—have been synthesized, and their thermal curing ability in solution and solid-state were investigated. The results reveal that the chemical reactivity of the aziridine-based curing resins is fine-tunable by controlling the N-substituent of aziridine. These curing resins undergo ring-opening polymerization under unprecedentedly mild conditions and show remarkably rapid curing rate, wide substrate scope and excellent chemoselectivity, as compared to the analogous epoxy agents.
