Using high resolution 1H-NMR spectroscopy,the article studied on rubber microstructure of PB,PI,SBS,SBR and SIBR .The analysis of the microstructure of SIBR is more fine than literature. The method is fast and accurate,which is suitable for the analysis of scientific research and production.%本文是在查阅文献及化学计算的基础上,利用高分辨率核磁共振氢谱对不同胶种聚丁二烯、聚异戊二烯、溶聚丁苯橡胶和苯乙烯-异戊二烯-丁二烯共聚物等的微观结构进行了较准确的定性和定量分析,其中对苯乙烯-异戊二烯-丁二烯的微观结构的剖析比所见到的文献更精细,这对橡胶微观结构及其使用性能之间关系的研究具有很重要的意义。该方法快速、准确,适合于科研与生产的中控分析。
