摘要：

The thermal decomposition of some polyimides containing pendent azobenzene groups was investigated with dynamic thermogravimetric analysis. Thermal degradation of azopolyimides took place in two or three steps. Traditional nonisothermal experiments involved linearizing an equation in some manner and fitting the resulting straight line to obtain the activation energy (E-a). The variation in activation energy with conversion degree of these polymers, obtained from two different kinetic methods, such as Flynn-Wall-Ozawa and Friedman, were compared and discussed.
