    Abstract: A furan-based polyamide is prepared by the following steps: (1) preparing a furan-based oligomer of formula (1) H2N—R—(NH—CO—F—CO—NH—R)n—NH2 (1) where R is a hydrocarbon moiety and F is a furan (cyclo-C4H2O) moiety and n represents the average degree of oligomerization, and where n is within the range of 1 to 10 by reacting 2,5-furandicarboxylic acid or its derivative with a diamine at a temperature of at most 100° C.; (2) contacting the oligomer of step (1) with a bifunctional linker selected from an acid or a derivative thereof where the acid is furandicarboxylic acid or a non-aromatic dicarboxylic acid; provided that if the hydrocarbon moiety R is aromatic, then the bifunctional linker is an aromatic dicarboxylic acid or a derivative thereof, at a mole ratio of the oligomer to the difunctional linker within the range of 0.8 to 1.5 at polycondensation conditions, and (3) isolating the resulting polyamide.

    Abstract translation: 通过以下步骤制备呋喃基聚酰胺:(1)制备式(1)的呋喃基低聚物H 2 N-R-(NH-CO-F-CO-NH-R)n -NH 2(1)其中 R为烃部分,F为呋喃(环C 4 H 2 O)部分,n为平均低聚度,n为1〜10的范围,通过使2,5-呋喃二羧酸或其衍生物与二胺 在至多100℃的温度下进行。 (2)使步骤(1)的低聚物与选自酸或其衍生物的双官能接头接触,其中酸是呋喃二甲酸或非芳族二羧酸; 条件是如果烃部分R是芳族的,则双官能连接体是芳族二羧酸或其衍生物,在低聚物与双官能接头的摩尔比在缩聚条件下为0.8至1.5的范围内,和(3) 分离得到的聚酰胺。
