Thermosets are an important class of materials that provide excellent temperature and solvent resistance; however, their high dimensional stability precludes degradation or reprocessing. While traditional thermoplastics can be mechanically and chemically recycled, these pathways are often elusive for resins due to their intrinsic structure. The renewed demand for sustainable polymers from public, industry and government stakeholders has increased research into (bio)degradable thermoplastics, but thermosets have often been overlooked. Aliphatic polyesters and polycarbonates are the cornerstone of biodegradable polymers, yet offer an arguably greater potential in thermosets as end-of-life options are more limited for these materials. This review summarises the most recent advances in the synthesis and characterisation of degradable thermosetting polyester and polycarbonate materials, including partially degradable systems derived from renewable resources such as itaconic acid or isosorbide. The review is organised by synthetic methodology including one-pot reactions and multi-step approaches making use of pre-polymers. Photo-cross-linking and high-energy irradiation are also discussed as emerging synthetic strategies.

固有可降解的交联聚酯和聚碳酸酯：树脂宜人

热固性材料是一类重要的材料，可提供出色的温度和耐溶剂性。但是，它们的高尺寸稳定性避免了降解或后处理。尽管传统的热塑性塑料可以进行机械和化学回收，但由于其固有的结构，这些途径对于树脂通常是难以捉摸的。公共，行业和政府利益相关者对可持续聚合物的新需求增加了对（生物）可降解热塑性塑料的研究，但热固性塑料常常被忽略。脂肪族聚酯和聚碳酸酯是可生物降解聚合物的基石，但由于这些材料的寿命终止选择受到更多限制，因此在热固性材料方面具有更大的潜力。这篇综述总结了可降解热固性聚酯和聚碳酸酯材料在合成和表征方面的最新进展，包括衍生自衣康酸或异山梨醇等可再生资源的部分可降解体系。该综述由合成方法进行组织，包括一锅法反应和利用预聚物的多步法。光交联和高能辐射也被讨论为新兴的合成策略。
