摘　　要：以呋喃和顺丁烯二酸酐为原料,经过D-A加成、亲核取代、脱环等一系列反应,得到新型聚酰亚胺二酐单体目标产物。通过核磁共振氢谱仪对中间体和二酐单体进行了结构表征,表征结果证实成功合成了中间体及目标产物。溶解性测试表明,二酐单体在常用溶剂中的溶解性能良好,有利于后续聚酰亚胺的合成。Furan and maleic anhydride as solvent,a new target product of dianhydride monomer was synthesized by D-A addition,nucleophile substitution and decyclization,etc.The structures of intermediates and dianhydride monomer were characterized by^1H-NMR spectra,and indicated that the synthesis was successfully performed.This target product can dissolved in common solvent on the basis of the solubility test which was very helpful for the subsequent synthesis of polyimide.
