摘要：

<正>Di（4-bromophenyl）ketone and various aromatic diamines as the monomers,a series of novel poly（imino ketone）s （PIKs）have been synthesized via palladium-catalyzed aryl amination,which is Hartwig-Buchwald polycondensation reaction.The structures of PIKs are characterized by means of elemental analysis,FT-IR,1H-NMR and UV-Vis spectroscopy. The results show a good agreement with the proposed structure.The general properties of PIKs are studied by DSC,TG and wide-angle X-ray diffraction,the solubility behavior is measured at polymer concentration 5 mg·mL-1.It is obvious that PIKs show high glass transition temperature（Tg>220℃）,good thermal stability with high decomposition temperatures （TD>480℃）and excellent solubility.
