Abstract: The homopolymer of 3-azidomethyl-3-nitratomethyloxe (PAMNO ) was prepared with boron trifluoride etherate (BF3. Et2O) as an initiator and butane 1, 4-diol (BDO ) as a co-initiator. Its decomposition temperature, decomposition enthalpies, glass transition temperature, and compatibility with HMX, HNIW, Al, and AP were measured by DSC. At the same time, the friction and impact sensitivities of PAMNO were evaluated by corresponding sensitivity measurements. The glass transition temperature of PAMNO is low, and its decomposition temperature and enthalpy are relative1y high, as well as its thermal stability better. The polymer has a good compatibility with HMX, HNIW, Al and AP etc. PAMNO is a potential binder for high energy solid propellant formulations.
