摘要：用热重分析法对不同相对分子质量的聚苯乙烯的热降解反应进行了研究。结果表明，在Ｎ_２气流，升温速率为５、１０、１５、２０℃／ｍｉｎ的条件下，聚苯乙烯的热降解机制为Ｄ_３和Ａ_（０．６），热降解活化能随聚苯乙烯相对分子质量而变化。
The kinetics of the thermal degradation of polystyrene with various moleculer weight was studied at heating rate of 5,10,15,20℃/min at the fluid of N_2.It was found that the models of the thermal degradation of polystyrene were D_3 and A_(0.6) It was also found that the activation energy and the degradation mechanism varied with the molecular weight of polystyrene.
