Using aromatic bis(4‐bromophenyl) ether and various aromatic diamines as the monomers, a series of novel poly(amine ether)s (PAEs) have been synthesized via palladium‐catalyzed aryl amination, which is the Hartwig‐Buchwald polycondensation reaction. Their structures were characterized by means of elemental analysis, FT‐IR, 1 H NMR and UV‐Vis spectroscopy. The results show a good agreement with the proposed structures. Their general properties were studied by DSC and TG, and it′s obvious that they show high glass transition temperatures ( T g >200 °C), good thermal stability with high decomposition temperatures ( T D >500 °C) and excellent solubility. The mechanical behavior of these polymers suggested that they could be considered a new class of high‐performance polymers.
