Cyclic macromolecules do not feature chain ends and are characterized by a higher effective intramolecular repulsion between polymer segments, leading to a higher excluded‐volume effect and greater hydration with respect to their linear counterparts. As a result of these unique properties, hydrogels composed of cross‐linked cyclic polymers feature enhanced mechanical strength while simultaneously incorporating more solvent with respect to networks formed from their linear analogues with identical molar mass and chemical composition. The translation of topology effects by cyclic polymers into the properties of polymer networks provides hydrogels that ideally do not include defects, such as dangling chain ends, and display unprecedented physicochemical characteristics.

环状聚（2-恶唑啉）生成的水凝胶显示出独特的溶胀和机械性能

环状大分子不具有链端，其特征是聚合物链段之间的分子内排斥力更高，与线性对应物相比，其排斥体积效应和水合性更高。由于这些独特的性质，由交联的环状聚合物组成的水凝胶具有增强的机械强度，同时相对于由其线性类似物形成的具有相同摩尔质量和化学组成的网络，同时引入了更多的溶剂。环状聚合物将拓扑效应转化为聚合物网络的特性，可提供理想情况下不包含缺陷（如悬链末端）的水凝胶，并显示出前所未有的理化特性。
