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.
