研究3─叠氮甲基─3─硝酸酯甲基氧丁环均聚醚(PAMNO)的合成及性能.采用BF3·Et2O作引发剂,BDO为助引发剂,合成出均聚醚PAMNO.采用DSC测定了PAMNO的分解温度、分解焓、玻璃化温度、及其与HMX,HNIW(六硝基六氮杂异伍兹烷),Al及AP的相容性.测定了PAMNO的机械感度,PAMNO的玻璃化温度低、分解温度和分解焓较高,常温下热稳定性较好,能与HMX,HNIW,AI及AP相容.PAMNO具有用作高能固体推进剂含能粘合剂的潜力。
Study on the Synthesis and Properties of 3-Azidomethyl-3-Nitrate Methoxybutyl Homopolyether (PAMNO). Using BF3 · Et2O as initiator and BDO as initiator, homopolyether PAMNO was synthesized. The decomposition temperature, decomposition enthalpy, glass transition temperature and the compatibility of PAMNO with HMX, HNIW, Al and AP were determined by DSC. The mechanical sensitivities of PAMNO were determined. The glass transition temperature of PAMNO was low, the decomposition temperature and enthalpy of decomposition were high, and the thermal stability was good at room temperature. It could be compatible with HMX, HNIW, AI and AP. PAMNO has the potential to be used as an energetic binder for high energy solid propellants.
