This article presents partially bio‐based unsaturated polyester resins (UPR) based on 2,5‐furandicarboxylic acid (FDCA). Three different FDCA‐based resins are prepared, which are potentially suited as i) general purpose resin (composed of 1,2‐propylene glycol), ii) resin for pultrusion (composed of diethylene glycol and 1,2‐propylene glycol), and iii) resin for pipe liners (composed of neopentyl glycol and 1,2‐propylene glycol). The mechanical and thermal properties of the bio‐based UPR are systematically investigated and compared with analogous fossil‐based UPR composed of phthalic and isophthalic acid, signaling comparable or even better properties for the bio‐based resins depending on the application targeted.

2,5-呋喃二甲酸作为不饱和聚酯树脂结构单元的评价

本文介绍了基于 2,5-呋喃二甲酸 (FDCA) 的部分生物基不饱和聚酯树脂 (UPR)。制备了三种不同的 FDCA 基树脂，它们可能适合用作 i) 通用树脂（由 1,2-丙二醇组成），ii) 拉挤成型用树脂（由二甘醇和 1,2-丙二醇组成），以及iii) 管道内衬用树脂（由新戊二醇和1,2-丙二醇组成）。对生物基 UPR 的机械和热性能进行了系统研究，并与由邻苯二甲酸和间苯二甲酸组成的类似化石基 UPR 进行了比较，表明生物基树脂根据目标应用具有可比甚至更好的性能。
