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: Polyamides are made from the polycondensation of monomers including from 15 to 80 mol % of 2,5-furandicarboxylic acid (FDCA), from 20 to 85 mol % of at least one aromatic dicarboxylic acid and from 50 to 100 mol % of at least one aliphatic diamine selected from those including 6 and 7 carbon atoms. A process allowing the synthesis of high molecular weight polyamides made from the above mentioned monomers is also described. Finally, compositions and articles including the same polyamides are also disclosed.
