| 摘 要： | 研究了苯乙烯／双（２，３－二溴丙基）反丁烯二酸酯共聚动力学，分别讨论了单体的配比，聚合温度，引发剂浓度对共聚合体系的转化率－时间曲线的影响，结果发现，聚合温度和引发剂浓度影响很大，单体的配比影响较小。所建立的反应速率模型可以对转化率小于２０％的聚合速率进行描述，而在高转化率下，由于凝胶效应的影响而难以准确描述。

| Abstract: | The copolymerization kinetics of styrene and bis ( 2,3 -dibromo -propyl) fumarate (FR-2) has been studied in this paper. Various factors that influence the copolymerization rate such as polymerization temperature, initiator concentration and content of FR -2 have been discussed respectively. The experimental results demonstrated that the polymerization rate increased slightly with increasing the content of FR-2, while increased rapidly with raising the polymerization temperature and initiator concentration. The model established on the basis of bulk copolymerization mechanism could be used to predict polymerization rate under the conversion below 20% , but failed to predict it above 20% due to the effect of gel. |
