Studies of Thermal Stability and Non-Isothermal Decomposition of Viologan Polymers

根据 TG- DTG曲线 ,通过微分法和积分法得到了紫精聚氨酯的动力学参数 ,通过比较所对得到的动力学参数 ;提出了最可能的机理函数 :f(α) =1- α; f(α) =32 (1- α) 43 / [(1- α) -13 -1];f(α) =12 (1- α) 3 .并求得了动力学补偿效应的数学表达式 :ln A=0 .2 157E- 6 .94

Studies of the thermal stability and non\|isothermal decomposition of voilogen polymers are carried out by thermogravimetry.The kinetic parameters were obtained by integral and differential methods.The most probable kinetic model functions were suggested by comparison of the kinetic parameters.And the mathematical expressions for the kinetic compensation effect were derived.Also some valuable results were obtained and discussed.
