    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.

    Abstract: An acid composition comprising 2-formyl-furan-5-carboxylic acid and 2,5-furandicarboxylic acid is purified in a process which comprises; contacting the acid composition with an alcohol to obtain an esterified composition; and separating the ester of 2-formyl-furan-5-carboxylic acid from the esterified composition to obtain a purified esterified product; and contacting the purified esterified composition with water for saponification or hydrolysis, to obtain a product composition, comprising 2,5-furandicarboxylic acid and a reduced amount of 2-formyl-furan-5-carboxylic acid.
