Abstract
Polyamideimides were prepared by reacting the diacidchloride of N-(p-carboxy phenyl) trimellitimide and ethylene diamine or hexamethylene diamine at 30–70°C. The polymers were characterized by nitrogen analyses and IR spectra. The solution, thermal, electrical, and a few other properties of the polymers were studied. The polymers were found to be soluble in highly polar solvents. The solubility parameter was calculated from Small's group contribution which agrees well with the experimental value. X-ray diffraction data indicated that the polymers are crystalline. Tg of the polymers calculated from DTA curves was found to be above 225°C. Dielectric behavior of the polymers was also studied at room temperature (∼30°C).Keywords
