摘要
通过傅-克酰基化反应合成了1,4-双-(4′-溴苯酰基)苯。以1,4-双-(4′-溴苯酰基)苯和芳香二胺为单体,通过钯催化的胺基化反应缩聚合成了新型高性能聚合物——聚亚胺酮(PIKs)。其结构由红外和核磁氢谱表征,表征结果与目标结构吻合良好。通过差示扫描量热仪(DSC)和热重分析(TG)等对PIKs的主要性能进行了测定,研究表明:该系聚合物有较高的玻璃化转变温度(Tg>230℃)、良好的热稳定性(高的热分解温度TD>500℃)及优秀的的溶解性能,其中PIK-3在室温下(20℃)可溶解在普通有机溶剂三氯甲烷(CHCl3)中。
1,4-bis-（4-bromobenzoyl）benzene was synthesized by Friedel-Crafts benzoylation reaction. Novel poly（imino ketone） s （PIKs） as high performance polymers were obtained by the condensation polymerization of 1,4-bis-（4-bromobenzoyl）benzene and aromatic diamines as the monomers via palladium-catalyzed amination reaction. The strcture of PIKs are characterized by means of FT- IR and ^1H-NMR spectroscopy, and the results agree with the proposed purpose structure. DSC and TG measurements show that PIKs possess high glass transition temperature（Tg〉230℃）, good thermal stability with high decomposition temperatures（TD〉500℃） and excellent solubility. PIK-3 can be dissolved in common organic solvent CHCl3 at room temperature（20℃）.
