利用Aspen Tech Inc.的polymer plus建立了本体聚苯乙烯聚合反应过程模型,利用其灵敏度分析方法对影响产品产量和分子量的引发剂浓度、反应温度等因素进行分析,得出了引发剂量的增加可以提高产量同时分子量下降;链转移剂量的增加使产量和分子量均下降;在首釜温度115℃和107℃出现Mn和Mw的最大值.
Polymerization process model of bulk polystyrene was established by polymer plus of Aspen Tech Inc.. The sensitivity analysis method was used to analyze the factors such as initiator concentration and reaction temperature, which affected the product yield and molecular weight. It was found that the increase of initiator dosage Increase the yield and decrease the molecular weight at the same time. The increase of chain transfer dose decreased both the yield and the molecular weight. The maximal values of Mn and Mw appeared at the first pot temperature of 115 ℃ and 107 ℃.
