摘　　要：用热重法(TG)研究了4种苯甲酰丙酮合铜和1,1,1-三氟-3-(2-噻吩基)丙酮合铜的偶氮二吡啶一维长链聚合配位化合物在动态氮气气氛下的热行为,结合元素分析和能谱技术,确定了各步分解的组分,并讨论了其晶体结构与热性质的关系。应用新的非线性等转化率法,并结合其他方法考察了各步分解反应的属性,进行了动力学分析,并试对传统动力学方法的适用性进行了讨论。TA study on the four one-dimensional chain copper complexes with benzoylacetone or 1,1,1-tri fluoro-3-(2-thenoyl)-acetone bridged through azobispyridine ligands was carried out in a dynamic nitrogen atmosphere. Supplemented by using both elemental analysis and EDS techniques, their thermal behavior and the composition of their intermediate products were examined and discussed in connection with their crystal structure. Thermal decomposition kinetics was investigated employing a newly proposed non-linear isoconversional method, together with four other kinetic methods. The usability of conventional kinetic method was also discussed.
