| 摘 要： | 在归属模型聚合物~1H-NMR谱的基础上建立了计算丁苯共聚物中非嵌段苯乙烯(NBSt)、嵌段苯乙烯(BSt)、1,2-丁二烯(1,2-Bd)和1,4-丁二烯(1,4-Bd)四个结构单元百分组成的标准,对标准样品的测定结果表明,用不饱和区质子峰积分面积可准确计算丁苯共聚物的结构组成,并据此测定了12个钨系催化丁苯共聚物的结构组成。

| Abstract: | Based on the standard ~1H - N. M. R spectra of model polymers of polybutadiene and polystyrene, the methods for the calculation of the content of the four types of structural units in copolymer of butadiene - styrene i. e. non - block styrene, block styrene, 1, 2 - butadiene and 1, 4 -butadiene, were established. The structure and composition of the copolymers could be calculated exactly from the areas under the peaks which correlated with the number of unsturated protons contribution to them. Also, the methods were applied to the determintion for twelve copolymers obtained from the copolymerization of butadiene and styrene with tungsten catalyst system. |
