The results suggest that thethermal decomposition kinetics of three chelate polymers are all of first order. Their averageactivation energy values of the thermal decomposition calculated by Ozawa-(I) method are 110,79, 136. 98 and 163. 64 kJ mol<sup>-1</sup> respectively, which increase linearly with the metal valence of themetal chelate展开更多
