摘要: 本文研究了由四氯化硅和氯硅烷等偶联聚合的多种星型支化SBS及其氢化试样的1H和13C-NMR谱,确定了它们的三种不同支化度的星型支化结构。并研究了四官能度星型支化SBS试样的13C序列结构。

Abstract: The branch structures of three kinds of star-type branched SBS block copolymer which were prepared by using different Chloro-Si-Ianes Coupling Agents, were determinted by comparing the 1H and 13C-NMR of them with those of their hydrogenated samples. The sequence structure of four arm star-type branches SBS was studied by 13C-NMR.
