合成了两种松香酸衍生物作为刚性单体与丙烯酸酯环氧化大豆油(AESO)共聚。然后制备了性能良好的全生物基热固性树脂。作为对比，石油基二乙烯基苯(DVB)也被用来与相同的AESO共聚。合成的松香衍生物的化学结构在聚合前用1H核磁共振、13C核磁共振和FT-IR确证。用差示扫描量热仪(DSC)、动态力学分析(DMA)和热重分析(TGA)对所得热固性树脂的力学性能和热性能进行了研究。结果表明，与松香衍生物共聚后，AESO的玻璃化转变温度、拉伸强度和定伸应力显著提高。松香酸衍生物在制备大豆油基热固性树脂方面显示出很大的潜力来替代石油基刚性化合物。为如何设计和合成更多性能令人满意的可再生热固性材料提供了重要信息。
Two kinds of rosin acid derivatives were synthesized to serve as the rigid monomers to copolymerize with acrylated epoxidized soybean oil (AESO). Full bio-based thermosetting resins with satisfactory properties were then prepared. For comparison, petroleum-based divinylbenzene (DVB) was also used to copolymerize with the same AESO. The chemical structures of the synthesized rosin derivatives were confirmed by 1H NMR, 13C NMR and FT-IR before polymerization. The mechanical and thermal properties of the resulting thermosets were investigated by differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA). Results demonstrated that the glass transition temperatures, tensile strength and modulus of the cured AESO were significantly improved after copolymerization with the rosin derivatives. The rosin acid derivatives showed great potential to replace petroleum-based rigid compounds for preparing soybean oil-based thermosets. The important information about how to design and synthesize more renewable thermosets with satisfactory properties was provided in this study.
