The biophenol molecule isoeugenol has been shown to be a major product of lignin-first reductive catalytic fractionation (RCF) of lignocellulosic biomass. The use of isoeugenol as a starting material for biobased polyesters is described here. A series of novel biobased polyesters have been synthesized from lignin-derived bisphenol and various acyl chlorides via a polycondensation reaction. NMR spectroscopy was used to confirm the structure as well as to approximate molecular weight. Thermal properties of the resulting biopolyesters are directly related to the length of the aliphatic chain of the diacid. Glass transition temperatures were in the range from 19 °C to 108 °C and can be tuned to be more in line with that of petroleum-based polyesters such as PET (T_g = 80 °C) by employing mixtures of lignin-based bisphenols (T_g = 83 °C). In addition to thermal tunability, these renewable polyesters can have up to 100% bio-content by mass.

生物酚分子异丁香酚已被证明是木质纤维素生物质的木质素优先还原催化分馏 (RCF) 的主要产物。这里描述了使用异丁香酚作为生物基聚酯的起始材料。由木质素衍生的双酚和各种酰氯通过缩聚反应合成了一系列新型生物基聚酯。NMR光谱用于确认结构以及近似分子量。所得生物聚酯的热性能与二酸的脂肪族链的长度直接相关。玻璃化转变温度在 19 °C 至 108 °C 的范围内，并且可以调整为更符合石油基聚酯（如 PET (T _g = 80 °C) 通过使用基于木质素的双酚混合物 (T _g  = 83 °C)。除了热可调性之外，这些可再生聚酯的生物含量最高可达 100%。
