Abstract

Semiaromatic polyesters derived from petroleum are an important class of polymers that encompass a wide variety of thermal and mechanical properties. Unfortunately, replacing the aromatic component with cost-competitive bioderived monomers is an ongoing challenge. This work describes the synthesis of nine different polyesters made from AB monomers that can be derived from lignin, starting with phloretic, coumaric, and ferulic acids and similar derivatives. The polyesters were synthesized at >50 g scale, and full characterization of the thermal, mechanical, and rheological properties is included. The polymers exhibit excellent thermal stability, a T_g range of 16–65 °C, tensile moduli ranging from 4.6 to 1200 MPa, and elongation at break ranging from 7.5% to greater than 3800%. To examine the effects of structural permutations among the polymer series, TTS master curves were constructed for seven polyesters using melt rheology. Properties such as packing length and characteristic ratio are described and compared among the series. Finally, it is demonstrated that these polyesters are easily chemically recycled to monomer in high yield.

木质素衍生半芳香族聚醚酯的结构-性能关系

从石油中提取的半芳香族聚酯是一类重要的聚合物，具有广泛的热性能和机械性能。不幸的是，用具有成本竞争力的生物衍生单体取代芳香族成分是一个持续的挑战。这项工作描述了由木质素衍生的AB单体合成的九种不同聚酯，从根木酸、香豆酸和阿魏酸及其类似衍生物开始。聚酯是在50克尺度下合成的，并对其热、力学和流变性能进行了全面表征。该聚合物具有优异的热稳定性，Tg范围为16 ~ 65℃，拉伸模量为4.6 ~ 1200mpa，断裂伸长率为7.5% ~ 3800%以上。为了研究聚合物系列之间结构排列的影响，利用熔体流变学方法构建了7种聚酯的TTS主曲线。对不同系列填料的填料长度、特性比等性能进行了描述和比较。最后，证明了这些聚酯很容易被化学回收成单体，收率很高。

期刊介绍： Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
