WebApr 11, 2024 · The strain energy of aziridine, 113 kJ/mol, is the same high as that of ethylene oxide. Aziridine can be polymerized via cationic ROP to yield hyperbranched polyethyleneimine. N-substituted aziridine monomers can be also polymerized by cationic or anionic ring-opening polymerization, and yield the corresponding liner polymers [8]. WebAziridine is a highly reactive strained ring that allows the synthesis of diverse small molecules. However, few studies have been reported to utilize aziridine to achieve the structural diversity of polymers. Herein, we report an aziridine-based multicomponent polymerization approach toward building-block diversity, and architectural diversity.
