Thermogravimetric analysis was performed to obtain thermal degradation kinetics of poly-alpha-methylstyrene(PAMS) at different heating rates in nitrogen. Several conclusions can be obtained from the experimental. Firstly, the degradation of PAMS is a one step reaction. Secondly, when the heating rate is 10 ℃/min , the main degradation temperature ranges from 302.79 ℃ to 343.10 ℃, and maximum thermal weight loss rate temperature is 325.85 ℃. The main degradation temperature ranges tend to higher temperature with increasing of heating rate. The kinetic parameters of thermal decomposition of PAMS were calculated using Kissinger method, Flynn-Wall-Ozawa method, and Coats-Redfern method.
