| 中文摘要: |
| 基于Arrhenius理论及相关公式 ,推导出表观活化能与幂指数相对变化关系。这种相对变化关系与聚苯乙烯热降解、热氧化降解、及其在各种添加剂情形下热降解动力学参数变化特征完全吻合. |
| 英文摘要: |
| The derivative expression between activation energy (E) and exponent (n) was deduced based on empirical equation. It was found that the increase of activation energy results in the decrease of exponent, vice versa. The two parameters were involved in the analysis of the thermal degradation pathway and mechanism of polystyrene. The degradation kinetics of polystyrene complied with the prediction of the derivative expression. In addition, the effects of temperature, atmosphere and additives on the kinetics of polystyrene were briefly discussed。 |
