Photocatalytic upcycling and depolymerization of vinyl polymers have emerged as promising strategies to combat plastic pollution and promote a circular economy. This mini review critically summarizes current developments in the upcycling and degradation of vinyl polymers including polystyrene and poly(meth)acrylates. Of these material classes, polymethacrylates possess the unique possibility to undergo a photocatalytic depolymerization back to monomer under thermodynamically favourable conditions, thus presenting significant advantages over traditional thermal strategies. Our perspective on current formidable challenges and potential future directions are also discussed.
乙烯基聚合物的光催化升级循环和解聚已成为应对塑料污染和促进循环经济的有前景的策略。本综述批判性地总结了乙烯基聚合物（包括聚苯乙烯和聚（甲基）丙烯酸酯）升级循环和降解的当前进展。在这些材料类别中，聚甲基丙烯酸酯具有在热力学有利条件下通过光催化解聚回到单体的独特可能性，因此相对于传统热策略具有显著优势。我们还讨论了当前严峻挑战和未来潜在方向的观点。
