尽管环状聚合物的组成与线性聚合物相当，但与线性聚合物相比，环状聚合物因其独特的物理性能而引起了人们的极大兴趣。在合成上，环状聚合物可以通过大环闭环或通过扩环聚合来获得，但这两种方法的主要挑战是生产高纯度的环状聚合物样品。这一重点介绍了在环状聚合物合成领域的进展，特别是对扩环复分解聚合。还讨论了表征环状聚合物和评估其纯度的方法，以强调需要额外的强大和可靠的方法合成和研究拓扑复杂的大分子。(c)2018 Wiley Periodicals，Inc. J.波利姆科学，A部分：聚合物Chem. 2019，57，228 - 242
Cyclic polymers have drawn considerable interest for their peculiar physical properties in comparison to linear polymers, despite their equivalent compositions. Synthetically, cyclic polymers can be accessed through either macrocyclic ring-closure or by ring-expansion polymerization, but the main challenge with either method is the production of highly pure cyclic polymer samples. This highlight describes advances in the area of cyclic polymer synthesis, with a particular focus on ring-expansion metathesis polymerization. Methods for characterizing cyclic polymers and assessing their purity are also discussed in order to emphasize the need for additional robust and reliable methods for synthesizing and studying topologically complex macromolecules.
