塑料用于我们日常生活所依赖的无数消费品中，已成为现代生活和全球经济不可或缺的材料。与此同时，目前不可持续的塑料生产和处置做法继续耗尽我们有限的自然资源，并在世界范围内造成严重的环境后果。为了寻求这些问题的可行解决办法，最近在开发化学可回收塑料方面取得了重大进展，这种塑料可以通过解聚回收积木化学品，重新聚合成原始质量的塑料，或创造性地重新用于增值材料。在这些可回收塑料中，来自可再生环酯的聚酯具有真正的潜力来应对这些挑战。因此，本综述从合成策略、材料性能，特别是化学可回收性方面，重点介绍了由常见的四元、五元、六元、七元和八元环酯衍生的塑料。这些研究最近发现了一种无限可回收的塑料，具有普通塑料的特性。
Plastics, used in countless consumer products that our daily lives depend on, have become indispensable materials essential for modern life and the global economy. At the same time, currently unsustainable practices in the production and disposal of plastics continue to deplete our finite natural resources and create severe worldwide environmental consequences. In the search for feasible solutions to these issues, significant recent advances have been made in developing chemically recyclable plastics, which allow for recovery of the building-block chemicals via depolymerization, for repolymerization to virgin-quality plastics, or for creative repurposing into value-added materials. Among such recyclable plastics, polyesters derived from renewable cyclic esters possess real potential to meet these challenges. Hence, this review highlights the plastics derived from common four-, five-, six-, seven-, and eight-membered cyclic esters by covering synthetic strategies, material properties, and, particularly, chemical recyclability. Such studies have culminated a recent discovery of infinitely recyclable plastics with properties of common plastics.
