Polymer of 2-acrolyl-quinazolin-carboxyl and homopolymer (PAQNH) complexes with Mn2+, Uo22+, Zr4+ and Nb5+ metals have been synthesized and characterized using different spectroscopic techniques (1H- NMR, IR and Uv-Vis) and magnetic measurements. The results obtained suggest that the metal ions dopping in dimmer monomer forming octahedral complexes. The thermal stabilities of dopping polymer complexes of AQNH with metal chlorides were studied thermally, The rates of polymerization of quinazoline acrolyl (PAQNH) in the absent and in presence of metal ions were studied. The activation parameters of the degradation of doping were discussed and calculated.
