| 摘 要： | 采用基团加和法估算了以聚叠氮缩水甘油醚(GAP)、聚硝酸酯缩水甘油醚(PGN)、聚2,2-双叠氮甲基氧杂环丁烷(PBAMO)、聚2-甲基-2-硝酸酯基氧杂环丁烷(PNIMMO)、2,2-双叠氮甲基氧杂环丁烷(BAMO)2-叠氮甲基2-甲基氧杂环丁烷(AMMO)共聚物(PBAMO/AMMO)等为软段,以二苯基甲烷二异氰酸酯、甲苯二异氰酸酯、异氟尔酮二异氰酸酯等为硬段,1,4-丁二醇为扩链剂的含能热塑性聚氨酯弹性体(ETPE)的生成焓.结果表明,随着硬段含量的增加,ETPE的生成焓降低,当硬段为MDI时,所制备的ETPE的生成焓高于其他硬段聚合物,叠氮化合物为软段的ETPE生成焓高于硝酸酯类化合物的.故通过对ETPE的能量预估和结构推断可以为设计具有高能量水平的ETPE提供依据.
