    摘要:

    2,5-呋喃二甲酸聚酯是以生物质平台化合物2,5-呋喃二甲酸为主要单体的生物基聚酯。本文主要介绍2,5-呋喃二甲酸聚酯的研究进展,对2,5-呋喃二甲酸聚酯的性能、合成方法、合成用催化剂及其共聚改性研究进行对比分析和讨论。2,5-呋喃二甲酸聚酯的玻璃化转变温度、热稳定性、杨氏模量和抗拉强度与对苯二甲酸聚酯的相应性能接近。同时,2,5-呋喃二甲酸聚酯及其共聚物对CO2、O2和H2O的阻隔性能优于对苯二甲酸聚酯,在许多领域是聚酯PET等材料的潜在替代物,受到了业界的广泛重视。然而,较低的断裂伸长率是2,5-呋喃二甲酸聚酯应用的瓶颈问题。共聚改性是改善2,5-呋喃二甲酸聚酯力学性能的有效办法之一,已有的共聚改性单体在改善2,5-呋喃二甲酸聚酯的断裂伸长率时使共聚物的杨氏模量和玻璃化转变温度大幅下降。合成具有较高断裂伸长率、较高杨氏模量和较高玻璃化转变温度的2,5-呋喃二甲酸聚合物是国内外学者亟待解决的难题,也是2,5-呋喃二甲酸聚酯共聚改性领域的重要研究方向。

    Abstract:

    2,5-furan dicarboxylate polyesters (FDCA polyesters) are bio-based polymers prepared by 2,5-furandicarboxylic acid as mainly intermediate which derived from renewable resources. In this review, the research progress of FDCA polyesters was introduced. The performances, synthetic methods, catalysts and copolymerization modification of FDCA polyesters were discussed. The glass transition temperatures (Tg), thermal stabilities, Young’s modulus and tensile strength of FDCA polyesters are similar to those of terephthalic acid (PTA) polyesters. FDCA polyesters also possess better CO2, O2 and H2O gas barrier prop-erties than PTA polyesters. FDCA polyesters have recently gained high interests due to their excellent properties, and may be potential substitute of PTA polyesters in many fields. However, FDCA polyesters lack of toughness, which significantly hinders its industry applications. Copolymerization was widely used to improve the mechanical properties of FDCA polyesters. In most cases, the copolymer’s elongations had been enhanced, however, the Young’s modulus and Tg declined rapidly simultaneously. It is still a chal-lenge and one of the most important subjects in FDCA copolymers to improve the elongations at break and achieve a higher Young’s modulus and a higher Tg at the same time.
