Abstract A library of α,ω-dienes has been prepared via Williamson ether synthesis from aromatic diols, which can be extracted from lignin as biosource or exhibit related structural motifs. These dienes were subsequently subjected to acyclic diene metathesis polymerisation (ADMET). The molecular characterisation of monomers and polymers was performed using NMR spectroscopy, GC–MS, and SEC. The influence of the monomer structure on the thermal properties of the phenolic polyether polymers was investigated by DSC. Glass transition temperatures (Tg) in the range of −44 to 18 °C were detected depending on the monomer structure while TGA analysis showed degradation temperatures between 160 °C and 300 °C. Tg-values could be further increased up to a value of 110 °C by fast and versatile post-modification with 1,2,4-triazolinedione (TAD) click chemistry. In addition, the characteristic double bonds of the ADMET-derived polymer chains allowed for crosslinking by this TAD chemistry.

通过 ADMET 合成的木质素启发酚类聚醚：系统结构特性研究

摘要 α,ω-二烯文库由芳香二醇通过威廉姆森醚合成制备，可以从木质素中提取作为生物来源或展示相关的结构基序。这些二烯随后进行无环二烯复分解聚合（ADMET）。单体和聚合物的分子表征使用 NMR 光谱、GC-MS 和 SEC 进行。通过DSC研究了单体结构对酚醛聚醚聚合物热性能的影响。根据单体结构检测到的玻璃化转变温度 (Tg) 在 -44 至 18 °C 的范围内，而 TGA 分析显示降解温度在 160 °C 至 300 °C 之间。通过使用 1,2,4-三唑啉二酮 (TAD) 点击化学进行快速和通用的后修饰，Tg 值可以进一步提高到 110 °C。
