Linear polyamides having viscosities in the range of 0.12-0.41 dl/g have been prepared from bisbenzoyl propionic acids and aromatic diamines by low temperature solution polycondensation in 80-85% yield. Their solubility characteristics were studied in various solvents e.g. DMF, DMAC, HMPT, H2SO4. These polyamides are amorphous in nature; their densities range from 1.2 to 1.8 g/cm3. Their thermal properties were examined by TGA and DTA. The two stage decomposition phenomenon observed in TGA is in agreement with the DTA results. The integral procedural decomposition temperatures were calculated and found to exceed 250 in almost all cases. © 1982.
