Poly(vinyl ether)s (PVEs) are typical products from living cationic polymerization. However, postpolymerization modification (PPM) and topological structure design of poly(vinyl ether)s under relatively mild conditions are rare, which limits their practical applications. Herein, we report a facile method to overcome this limitation by exploiting the selective addition reaction of electrophilic selenium reagent and divinyl monomers, which can produce PVEs with pendent vinyl groups in each repeat unit or end-functionalized PVEs. PPM of PVEs was realized by a thiol–ene click reaction. Furthermore, brush polymers and core cross-linked star polymers were successfully prepared by using end-functionalized PVEs as macromonomers, providing a general method for the preparation of topological polymers and laying a foundation for the development and application of PVEs.

基于亲电硒试剂与二乙烯基单体选择性加成反应的聚（乙烯基醚）后聚合改性及拓扑结构设计

聚（乙烯基醚）（PVE）是活性阳离子聚合的典型产物。然而，在相对温和的条件下，聚（乙烯基醚）的后聚合改性（PPM）和拓扑结构设计很少见，这限制了它们的实际应用。在此，我们报告了一种通过利用亲电子硒试剂和二乙烯基单体的选择性加成反应来克服这一限制的简便方法，该方法可以生产在每个重复单元中具有侧乙烯基的 PVE 或末端官能化的 PVE。PVE 的 PPM 通过硫醇-烯点击反应实现。此外，通过使用末端官能化的PVE作为大分子单体，成功制备了刷状聚合物和核心交联星形聚合物，
