Poly Quinazoline (2-acrolyl-phithalizinone-carboxyl) homopolymer (PAPNH) and polymer complexes of phithalizinone with Fe3+, UO22+ and Zn2+ metals have been prepared and characterized using spectral (1H-NMR, IR and Uv-vis) and magnetic measurements. The data suggest that the Fe3+, UO22+ and Zn2+ polymer complexes are octahedral dimer. The thermal stabilities of (PAPNH) homopolymer and polymer complexes of (APNH) with metal chlorides were studied thermogravimetrically. The rates of polymerization of (PAPNH) in the absence and in presence of metal chlorides were studied. The activation energies of the degradation of the homopolymer and polymer complexes were calculated using Arrhenius equation.
