摘　　要：以马来海松香酸作为封端剂合成了一系列新型聚酰亚胺(PI)低聚物,并对产物进行了结构表征。研究发现,该类聚合物显示了较好的热稳定性,其中PI–3的5%热失重温度达到340℃,在TDG曲线上显示了两个链段分解过程,分别对应于松香脂环结构和酰亚胺环结构的分解。A series of novel maleopimaric acid anhydride-endcapped imide oligomers were synthesized and the target oligomers were structurally characterized.The oligomers showed certain thermal stability, and the thermal decomposition temperature （ T5%） of PI-1 reached 340 ℃ .Two decomposition phases were observed in DTG curve of the oligomers, which correspond to the thermal fragmentation of alicyclic ring and that of imide structure.
