  • 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

  • Intrinsically gel-free, randomly branched polyamide
    Patent number: 6835799
    Abstract: The invention relates to a randomly branched polyamide comprising at least units derived from: 1. AB monomers, 2. at least one compound I, being a carboxylic acid (Av) having a functionality v≧2 or an amine (Bw) having a functionality w≧2, 3. at least one compound II, being a carboxylic acid (Av) having a functionality v≧3 or an amine (Bw) having a functionality w≧3, compound II being a carboxylic acid if compound I is an amine or compound II being an amine if compound I is a carboxylic acid and the amounts of all units derived from carboxylic acids and amines in the polyamide satisfying conditions as mentioned in claim 1. The composition of the randomly branched polyamide is such that it cannot form a crosslinked polyamide (and thus no gels, either), in particular during the prepolymerization, the polymerization, the post-condensation, the processing and the storage of the randomly branched polyamide, and this at a variety of ambient factors, for instance at elevated temperature and pressure.
