摘要：

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, H-1 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 degrees C), good thermal stability with high decomposition temperatures (T-D > 500 degrees C) and excellent solubility. The mechanical behavior of these polymers suggested that they could be considered a new class of high-performance polymers.
