Nowe aromatyczne poliamidoimidy - synteza oraz wlaściwosci termiczne i fotoluminescencyjne

New aromatic polyamideimides (PAD were synthesized by high temperature polycon-densation from diamidedianhydrides (formerly prepared by us) and diamines: 1,5-diaminonaphtha-lene, 4,4'-(hexafluoro-isopropylidene)-dianiline or 2,6-diamineanthraquinone. Chemical structures of PAI obtained (Fig. 1) were confirmed by FTIR (Fig. 2) and NMR (Fig. 3) methods and by elemental analysis. Polyamideimides studied showed high thermal stability both in nitrogen or air atmosphere as well as high glass transition temperature in the range 220-265 °C (Table 1). An evaluation of optical and photoluminescent properties of PAI in NMP solutions (Fig. 4 and 5) showed that they emit the light of wavelength in the range 405-572 nm, dependency on the structure.
