摘　　要：以1,4-双-(4′-溴苯酰基)苯和芳香二胺为单体,通过钯催化的胺化反应缩聚合成了高性能聚合物-聚亚胺酮(PIK-Ⅲ)。其结构由红外和核磁氢谱表征,结果与理论产物吻合良好。对PIK-Ⅲ的主要性能进行了测定,结果表明,该聚合物具有一定的耐热性能(Tg=233.09℃,TD>500℃)和优良的溶解性能。Poly（imino ketone）-3 （PIK-Ⅲ）, a novel polymer of high performance, was synthesized via palladium-catalyzed polycondensation reaction using 1,4-bis-（4-bromobenzoyl）benzene and aromatic diamine as monomers. The structure of PIK-Ⅲ was characterized by FT-IR and 1H NMR. The main properties of PIK-Ⅲ were studied by DSC and TG. It was showed that PIK-Ⅲ was of good thermal stability （Tg =233.09 ℃, TD 〉500℃）and excellent solubility.
