SYNTHESIS AND PROPERTIES OF NOVEL POLY(IMINO KETONE)S AS HIGH-PERFORMANCE POLYMERS

Received Date: 30 December 2006
Revised Date: 1 February 2007

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°C), good thermal stability with high decomposition temperatures (TD＞ 480°C) and excellent solubility.
