  • Polyamides containing the bio-based 2,5-furandicarboxylic acid
    Patent number: 9951181
    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.
    Type: Grant
