建立了苯乙烯本体热聚合过程模型，分析讨论了苯乙烯在连续搅拌槽式反应器中进行热引发本体聚合行为．分别讨论了聚合温度和停留时间对苯乙烯的转化率、聚合速率、产物的相对分子质量及其分布、粘度和密度的影响,结果表明，聚合温度决定产物的相对分于质量及其分布，且对转化率、聚合速率及粘度均有较大影响；停留时间对产物的相对分子质量及其分布无明显的影响，对转化率、密度及粘度有较大影响．聚合温度和停留时间是苯乙烯本体聚合过程中的两个至关重要的操作条件，同时为方便工程应用提供了经验关联式．
The thermopolymerization process model of styrene was established, and the thermal polymerization behavior of styrene in continuous stirred tank reactor was analyzed. The effects of polymerization temperature and residence time on the conversion of styrene, the polymerization rate, the relative molecular mass of the product and its distribution, viscosity and density were discussed. The results show that the polymerization temperature determines the relative mass and distribution of the product, and The conversion rate, polymerization rate and viscosity have a greater impact; residence time on the relative molecular mass of the product and its distribution had no significant effect on the conversion rate, density and viscosity have a greater impact. The polymerization temperature and residence time are two critical operating conditions in the bulk polymerization of styrene and provide an empirical correlation for the convenience of engineering applications.
