以2，5-呋喃二甲酸（FDCA）、衣康酸（IA）、琥珀酸（SA）和1，3-丙二醇（PD）为原料，通过直接缩聚反应合成了一系列生物基不饱和聚酯（bio-UPs）。通过傅立叶变换红外光谱和1H NMR鉴定生物UP的化学结构，然后将它们与生物基非挥发性活性稀释剂愈创木酚甲基丙烯酸酯（GM）一起固化。采用热重分析、三点弯曲试验和动态力学分析评价了固化生物UPs的热和力学特性。结果表明，FDCA的引入大大提高了固化生物UPs的热性能，弯曲强度和模量。5%热失重的温度达到330 ℃，弯曲强度和模量分别达到122.8和3521 MPa。这些结果表明，生物不饱和聚酯具有替代石油基不饱和聚酯的潜力。
A range of fully biobased unsaturated polyesters (bio-UPs) derived from 2,5-furandicarboxylic (FDCA), itaconic acid (IA), succinic acid (SA), and 1,3-propanediol (PD) were obtained via direct polycondensation. The chemical structures of the bio-UPs were identified by Fourier transfrom infrared spectroscopy and 1H NMR before they were cured together with a biobased, nonvolatile reactive diluent, guaiacol methacrylate (GM). The thermal and mechanical characterizations of the cured bio-UPs were evaluated using thermogravimetric analysis, 3-point bending tests, and dynamic mechanical analysis. Results showed that the thermal properties, flexural strength, and modulus of the cured bio-UPs were greatly improved after the introduction of FDCA. The temperature of 5% thermal weight loss reached 330 °C, and the flexural strength and modulus reached 122.8 and 3521 MPa, respectively. These results indicate that the bio-UPs have the potential to replace petroleum-based UPs.
