Photodegradable, recyclable, and renewable, crosslinked polymers from bioresources show promise towards developing a sustainable strategy to address the issue of plastics degradability and recyclability. Photo processes are not widely exploited for upcycling polymers in spite of the potential to have spatial and temporal control of the degradation in addition to being a green process. In this report we highlight a methodology in which biomass-derived crosslinked polymers can be programmed to degrade at ≈300 nm with ≈60 % recovery of the monomer. The recovered monomer was recycled back to the crosslinked polymer.
光降解、可回收、可再生的生物基交联聚合物有望为解决塑料的可降解性和可回收性问题提供一种可持续的策略。尽管光降解过程具有时空可控性，且绿色环保，但并未广泛应用于聚合物的升级回收。在本报告中，我们强调了一种方法，通过该方法可以控制生物质衍生的交联聚合物在 ≈300nm 处降解，同时 ≈60%的单体可以回收。回收的单体被循环回交联聚合物。
