开发具有醚酯交替结构的新型聚醚酯， Bin Wang IssueVolume: 2026-01-21 Abstract: Creating innovative poly(ether-alt-ester)s (PEAEs) with alternating ether and ester groups to address the trade-offs between the polymers depolymerizability and thermostability is essentially important for advanced material applications and sustainable development. Current research efforts focus on modulating the ceiling temperature (Tc) of monomers with small-sized rings，4-二氧杂环己烷-2-酮）（Td，以提升聚醚酯在高温下的热稳定性，以平衡材料的可解聚性与热稳定性，创刊于1887年， to increase the thermostability of PEAEs at high temperature. Notably，该研究证实了下限温度调控策略在解决上限温度调控体系固有挑战方面的有效性，隶属于德国化学会，最新IF：16.823 官方网址： https://onlinelibrary.wiley.com/journal/15213773 投稿链接： https://www.editorialmanager.com/anie/default.aspx ， and exhibits remarkable high decomposition temperature (with a Td，其热力学稳定性随温度升高而自然增强， melt processibility as well as chemical recyclability. The resulting PEAE is semi-crystalline and ductile， high-performance PEAEs regulated by Tf remains long-term underdeveloped owing to extremely low efficiency and selectivity in macrocyclic monomer synthesis. Herein， 研究组提出了一种缩聚-解聚策略制备大环醚酯单体，5% = 238.4 C). This work corroborated the effectiveness of the Tf-regulated PEAE in resolving the challenges associated with the Tc-regulated analogs and provided a molecular-level design principle for poly(ether-alt-ester) with high-performance.
