根据聚苯硫醚(PPS)聚合机理及过程分析并通过合理假设,提出了基于Monte Carlo方法的PPS聚合反应动力学模型。利用文献数据对模型参数进行了拟合回归,结果表明动力学模型计算值与相应的实验数据符合良好,并且模型外推预测与相同条件的实验接近,两者偏差小于2%;通过模型对反应物配比的影响进行模拟计算,结果与文献值相符合。最后,通过建立工业PPS聚合反应器模型对工业生产过程进行了模拟计算,结果表明PPS生产过程宜采用多釜串联的方式。相关研究结果可对PPS聚合反应动力学建模和工业过程的设计和优化提供理论依据。
Based on the polymerization mechanism and process analysis of polyphenylene sulfide (PPS) and reasonable assumptions
a kinetic model of PPS polymerization based on Monte Carlo method was proposed. The fitting regression of the model parameters was performed through literature data
and the results show that the calculated value based on the kinetic model is in good agreement with the corresponding experimental data
and the extrapolation prediction based on the model is consistent with experiments
with the deviation less than 2%. The effect of the reactants ratio on the polymerization reaction was calculated based on kinetic model
and the results is in accordance with the literature value. Finally
by establishing the reactor model of industrial PPS polymerization
the industrial production process was simulated
and the results show that the tanks-in-series mode should be adopted for this process. The relevant results in this work will provide theoretical basis to the kinetic modeling of PPS polymerization reaction and the design and optimization of industrial PPS production.
