摘　　要：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.The steady process simulation models of bulk polystyrene unit process were developed by the polymer process simulation software Polymer Plus of Aspen Tech Inc. The effect of changing of initiator, temperature, etc. on the product and Mn Mw were discussed by the sensitivity analysis. The result shows that higher concentration of initiator leads to higher production rate but the lower Mn and the higher flow rate of chain agent cause the lower product ion rate and Mn, Mn Mw reach the maximum at 115 ℃ and 107 ℃ of first reactor.
