本论文研究目标是在常规阴离子聚合方法合成sbs的基础上，通过端基转化实现了SBS与极性单体共聚。

Based on the general synthesis of SBS by anionic polymerization mechanism, we have carried out the copolymerization of SBS with several polar monomers by conversion of end-group of SBS.

This represents the upright struts on a ladder that I showed you before, it represents this backbone that's shown by - that's formed by polymerizing the pentose's together through phosphate's always going 5' to 3', 5' to 3'.

线条代表梯子,上下的支柱 之前给你们演示过,代表由多聚戊糖分子,通过磷酸基从5'端向3'端方向,连接起来的主链
