摘　　要：现代社会的发展越来越依赖高分子材料,但其大量使用后不当处置不仅造成资源浪费,更造成严重的生态环境问题.将废弃高分子材料解聚回单体,然后通过聚合反应重新生成与解聚之前等值的高分子材料,实现高分子材料循环利用被认为是解决上述问题的重要手段之一.近年来,通过单体设计发展“理想单体”从而调节“聚合—解聚”平衡,实现温和条件下高分子材料闭环回收的策略取得了长足进展.本文将从闭环回收聚酯、聚碳酸酯、含硫聚合物、聚环状烯烃等方面进行综述,并对该领域的挑战和未来发展方向进行简要讨论.The development of modern society highly depends on polymer materials.However,progressive usage and accumulation of polymer products caused the waste of resources and severe environmental issues.To address the abovementioned problem,the development of chemical recycling polymers that could transform the polymers back to monomers and repolymerize to produce polymer materials without value loss is an attractive and important strategy.In recent years,significant advances in the design of“ideal monomers”have enabled the regulation of“polymerization-depolymerization”equilibrium and achieved the closed-loop recycling under mild conditions.This review will focus on the closed-loop recycling of polyesters,polycarbonates,sulfur-containing polymers,and poly(cyclic olefin)s,illustrate the challenges of this field,and provide a perspective on the future development direction.
