| 摘要 |
Disclosed is a poly(amide-ether-imide) and the preparation of the same. An ether chain-containing aromatic diamine is subject to thermal condensation with trimellitic anhydride (TMA) in a polar solvent to obtain diimide dicarboxylic acid, followed by polycondensing the diimide dicarboxlic acid with diamine to form the poly(amide-ether-imide). The poly(amide-ether-imide) of the present invention has superior strength, heat resistance, and processability. The preparation of the present invention is simple and economic.
