摘要

We report the phosphorylation-assisted polymerization and characterization of 2,5-furandicarboxylic acid (FDCA)-based wholly aromatic polyamide. For this purpose, poly(3,4'-oxydiphenylene furanamide) (PODFA) was synthesized via solution polymerization of FDCA with 3,4'-oxydiphenylamine (ODPA) in the presence of triphenyl phosphite and pyridine. The spectroscopic analyses and solution viscosity measurement revealed the successful synthesis of a relatively high molecular weight PODFA with good solubility in a variety of polar aprotic solvents without inorganic salts. PODFA could be thus processed into purely amorphous films with high flexibility in bending and folding deformation. The 39 mu m thick PODFA film exhibited optical transparency, and the 65-100 mu m thick films showed a transparent yellow or light brown color. The amorphous PODFA films were characterized to have excellent thermal and static mechanical properties in terms of a glass transition temperature of similar to 260 degrees C, a thermal decomposition peak temperature of similar to 450 degrees C, a residue of similar to 50 at 800 degrees C under nitrogen gas condition, an initial modulus of 12.98 +/- 1.84 GPa, a tensile strength of 84.6 +/- 17.3 MPa, and a strain at break of 2.3 +/- 1.5 at room temperature.
