摘　　要：文章以4,4’-二溴对苯甲酮和4,4’-二氨基二苯醚为单体,三(二苄基丙酮)二钯为催化剂,通过Buchwald-Hartwig芳胺化反应,实现CAr-N偶联反应,合成了新型功能高分子聚亚胺醚亚胺酮。实现芳香二胺结构单元和二溴化芳香酮结构单元的共聚,对共聚物结构、基本性能进行表征,并研究CAr-N偶联构建对苯甲酮/芳基醚主链结构的可行性,探讨聚合物主链构型、热稳定性和其他性能等。In this paper,4.4’-dibromo-p-benzophenone and 4,4’-diaminodiphenyl ether were used as monomers,(dibenzylacetone)dipalladium as catalyst,CAr-N coupling reaction was realized by Buchwald-Hartwig aromatic amination reaction,and a new functional polymer poly(imino ether imide ketone)was synthesized to realize the copolymerization of aromatic diamine structural unit and dibromo aromatic ketone structural unit.The structure and basic properties of the copolymer were characterized.The feasibility of constructing the main chain structure of p-benzophenone/aryl ether by CAr-N coupling was studied,and the main chain configuration,thermal stability and other properties of the polymer were discussed.
