    A Study on Microsequence of Solution Styrene-Butadiene Copolymer by ~(13)C-NMR

    • 摘要: 本文利用~(13)C-NMR,对“准”稳态下以n-BuLi-THF引发的丁苯共聚物的序列结构进行了研究。获得了THF与n-BuLi在不同比例下产物的数均嵌段长度、混合单体嵌段长度和交替结构的变化情况。

       

      Abstract: By using the ~(13)C-NMR data, the sequential distribution of styrene-butadiene copolymer initiated by n-BuLi-THF under "quasi-stationary" condition has been investigated. Some important informations, such as average block lengths for monomer units and mixed monomer blocks, the variation of alternating microstructure etc., have been evaluated.
