Abstract: An improvement on the synthesis of 3-azidomethyl-3-nitratomethyloxetane(AMNO) was performed. With boron trifluoride etherate(BF3·Et2O) as an initiator and butane-1,4-diol(BDO) as a co-initiator, the homopolymerization of AMNOwas investigated in detail by a cationic ring opening polymerization process. The prepolymers show predictable molecular weights and low dispersities. The molecular structures of the polymer were characterized with FTIR, 1H NMRand GPC.

Key words: 3-Azidomethyl-3-nitratomethyloxetane, Cationic ring opening polymerization, Homopoly-merization, Characterization of structure
