To attain high performance aromatic polyamides with good thermal/mechanical property as well as facile processibility, a series of aromatic poly(ether amide)s were synthesized by using phosphorylation-based polycondensation reaction of 3,4'-oxydianiline, terephthalic acid, and isophthalic acid in NMP/CaCl2 solvent system. Molecular structure, thermal stability and mechanical properties of the aromatic poly(ether amide)s were investigated with aids of NMR/FT-IR spectroscopy, DSC/TGA, and DMA/UTM, respectively. It was characterized that the synthesized poly(ether amide)s exhibited excellent thermal stability, which was comparable with thermal properties of conventional aromatic polyamides, although they had excellent solubility in polar organic solvents such as NMP, DMSO, DMF and DMAc. |
