摘　　要：合成了一系列MAPO与HAc(乙酸 )比值不同的MH1～ 5,并考察了其对IPDI固化的高燃速丁羟推进剂低温力学性能的影响 ,研究发现MH对推进剂低温力学性能的影响和MAPO与HAc之比有关 ,初步认为MH对IPDI固化的高燃速丁羟推进剂低温力学性能没有明显改善作用。A series of MH derivatives with different MAPO/HAc (ethylic acid) ratio were synthesized and the effects of them on the low temperature mechanical property of high burning rate HTPB/IPDI solid propellant were studied. The results show that the effects of MH on the low temperature mechanical property of the propellant depend on with the ratio of MAPO and HAc. The addition of MH can't improve the low temperature mechanical property of high burning-rate HTPB IPDI propellant.
