摘　　要：通过对苯乙烯/双(2,3-二溴丙基)反丁烯二酸酯(St/FR-2)共聚体系的研究,用核磁共振氢谱方法分析了共聚物组成,运用Fineman-Ross的理论进行数据处理,得到了90℃下,FR-2与St的竞聚率分别为0.0269±0.0003和0.1200±0.0577。The reactivity ratios of copolymerization of styrene and bis(2, 3 - dibromo - propyl) fumarate (FR - 2) were determined with the method of Fineman - Ross. At the polymerization temperature of 90℃, the reactivity ratio of styrene and FR - 2 were 0.026 9 ± 0.000 3 and 0.120 0 ± 0.057 7, respectively. The polymerization temperature exerted little influence on the reactivity ratio. The compositions of the copolymer were analyzed by means of 1H-NMR.
