采用热重法进行了含阻燃添加剂的高抗冲聚苯乙烯塑料（flame retarded high impact polystyrene，Br-Sb-HIPS）在不同升温速率下的热解实验，建立了包含3个连续反应的阻燃HIPS热解动力学模型。通过Flynn-Wall-Ozawa法得到阻燃HIPS热解过程的活化能为103～307 kJ·mol-1，利用多元非线性无约束最优化方法求得模型参数。研究表明，Br-Sb-HIPS 3个反应的活化能和指前因子分别为191.632、213.263、238.331 kJ·mol-1和11.641、12.772、11.666 min-1。动力学模型能够很好地预测阻燃HIPS热解过程。

A thermo-gravimetric (TG) study of flame retarded high impact polystyrene( (Br-Sb-HIPS) pyrolysis was conducted at various heating rates(5 ℃·min-1 ,10 ℃·min-1 , 15 ℃·min-1). A kinetic model of the pyrolysis of flame retarded HIPS that contains three series reaction was built. The activation energy of pyrolysis reaction of flame retarded HIPS obtained by the method of Flynn-Wall-Ozawa changed between 103-307 kJ·mol-1. Parameters were solved by a multidimensional unconstrained nonlinear minimization method. The values of activation energy were 191.632, 213.263 and 238.331 kJ·mol-1 and the values of pre-exponential factor were 11.641, 12.772, 11.666 min-1 respectively for the three reactions. The kinetic model was able to accurately predict the pyrolysis process of flame retarded HIPS.
