摘要
用ＤＳＣ研究了ＰＡ１０１０／６共聚物初生态及次生态样品的熔融行为，发现初生态样品的高温熔融峰（Ｔ１）和低温熔融峰（Ｔ２）对组成有不同的依赖关系；首次发现ＰＡ１０１０／６共聚物次生态的冷结晶现象，并讨论了冷结晶温度（ＴＣ）、冷结晶时间（ｔｃ）与组成的关系．
Thermal decomposition of ammonium molybdate is studied by thermal gravimetric analysis(TG) and differential thermal analysis(DTA) The results indicate that ammonium molybdate is thermally decomposed in three steps: in the temperature range of 353～473K,the crystal water was mainly removed ,and the structure of ammonium molybdate is remained, in the temperature range of 473～573K,the crystal water could be completely removed while a fraction of the ammonium ions were lost to produce one kind of metastable molybdena species, at temperature above 573K, the residual ammonium ions could be completely removed, therefore rearrangement of the molybdena subsequently occurred to form the bulk phase of MoO 3
