摘　　要：利用真空安定性试验仪(VST)研究了ADN与端羟基聚丁二烯(HTPB)、3,3-双叠氮甲基氧丁环与四氢呋喃(BAMO-THF)聚合物、双基粘合剂(NG+NC)、聚乙二醇(PEG)、共聚醚粘合剂(PET)五种粘合剂的混合体系的相容性,还利用差示扫描量热仪(DSC)和拉瓦尔试验仪(LAWA)研究了其中的三种体系。这三种不同方法都一致判断ADN与(NG+NC)和PEG为不相容,但对AND/PET体系的相容性判断不一致,VST法判断为不相容,而LAWA和DSC法却判断为相容。从试验条件的差异,组分相互作用是发生在凝聚相还是在气相与凝聚相之间等方面,探讨了产生这种不同结论的原因。The compatibilities of ammonium dinitramide （ADN） with five kinds of the binders including hydroxyl terminated polybutadiene （ HTPB ） ,3,3-azidomethyl-3-methyloxetane-tetrahydrafuran （ BAMO-THF ）, nitroglycerine/nitrocellulose （ NG ＋ NC ）, polyethylene glycol （ PEG ） and poly （ epoxy ethane tertrahydrafuran ） （ PET ）, were studied by vacuum stability test （ VST ）. Meanwhile the compatibilities of ADN with three kinds of the binders were studied by DSC and LAWA techniques. The results show that the systems of PEG and （ NG ＋ NC） with ADN have strong reactivity and is rated to be incompatible using three methods. The system of PET with ADN is judged to be incompatible by VST, while to be compatible by DSC and LAWA. The reasons causing different conclusion from different methods were discussed.
