摘要：

Several aromatic polyamides were prepared from 4,4'-[sulfonyl bis(p-benzoyl)(p-phenyleneoxy)]dibenzoic acid with various diamines by the phosphorylation route. The polymers were characterized by elemental analysis, thermogravimetric analysis, differential scanning calorimetry and infra-red analysis. The polyamides, obtained in quantitative yield, possessed inherent viscosities in the range 0.3-1 dlg(-1) and 10% weight loss in nitrogen and air were above 460 and 440 degrees C, respectively. Most of the polymers were soluble in aprotic solvents. The effect of the structure on properties such as solubility and thermal behaviour were also studied. Copyright (C) 1996 Elsevier Science Ltd.
