A cyclic grafted polymer, as a novel and unique kind of polymer, possesses a cyclic backbone and linear grafted side chains. Their physical properties and conformations are controlled by steric hindrance from the grafted side chains. As a cyclic derivative, cyclic grafted polymers have been successfully prepared and characterized within the past decade. To the best of our knowledge, cyclic grafted polymers have not been systematically generalized and summarized. In this review, we illustrate the considerable advances in the architectural construction of cyclic grafted polymers with three different approaches, including “grafting through”, “grafting onto” and “grafting from”. Additionally, their potential applications are also briefly discussed.

环状接枝聚合物的结构及其潜在应用的最新进展

环状接枝聚合物作为一种新颖独特的聚合物，具有环状骨架和直链接枝的侧链。它们的物理性质和构象受接枝侧链的位阻控制。作为环状衍生物，在过去十年中已经成功地制备了环状接枝聚合物并对其进行了表征。据我们所知，环状接枝聚合物尚未得到系统的概括和总结。在这篇综述中，我们用三种不同的方法说明了环状接枝聚合物在建筑结构上的重大进展，包括“通过接枝”，“接枝到”和“从……接枝”。此外，还简要讨论了它们的潜在应用。
