Synthesis and properties of novel soluble poly(aryl amine ketone)s as high-performance polymers

A series of poly(aryl amine ketone)s have been obtained by the condensation polymerization of different aromatic dibromides with different primary aromatic diamines via palladium-catalyzed aryl amination reaction. The structures of polymers are characterized by means of FT-IR, 1 H NMR spectroscopy, and elemental analysis. The results show an agreement with the proposed structures. DSC and TG measurements show that polymers possess high glass transition temperature ( T g >170°C) and good thermal stability with high decomposition temperatures ( T D >450°C). These novel polymers also exhibit good mechanical behaviors and good solubility.
