酰亚胺键扩链的双马来酰亚胺的合成与表征

Preparation and Characterization of Bismaleimides Chain extented by Imide Linkage

用二苯甲酮四羧酸二酐（ＢＴＤＡ）和４，４′－二氨基二苯甲烷等反应，制备一系列酰亚胺键扩链的双马来酰亚胺。样品结构用质子核磁共振和红外光谱进行表征，其热性能用热重—差热分析测定。研究结果表明，核磁共振数据和红外光谱数据吻合，扩链的双马来酰亚胺具有好的热性能。

A series of bismaleimides chain extented by imide linkage were prepared by reacting benzophenone tetracarboxylic dianhydride with 4, 4 1 diaminodiphenyl methane et al. The structures of sample were characterized by proton nuclear magnetic resonance and infra red spectroscopy, and the thermal properties were measured by thermogravimetric analysis and dynamic thermal analysis. The results show that the nmr data were in agreement with the infra red, and the bismaleimides chain extented have good thermal stability.
