Aromatic polyamides are widely used in various industrial sectors including automobile, aerospace, electronics, etc. due to their exceptional mechanical and thermal properties. However, commercially available aromatic polyamides are synthesized from petroleum-based monomers and also have limited processability owing to their lack of general solubility in organic solvents. On continuing efforts to improve the solubility and environmental issue of aromatic polyamides, in this study, we have synthesized aromatic polyamides via phosphorylation-based polycondensation of an aromatic bio-based monomer, 2,5-furandicarboxylic acid, with fluorine-containing aromatic diamines. The molecular structures were investigated by 1H-NMR and FT-IR spectroscopy. The solubility and inherent viscosity are tested in commonly used organic solvents. The thermal transition and stability are also analyzed by TGA and DSC. |
