Thermally stable polymer which does not lose weight rapidly up to about 400℃ was prepared from p-aminobenzoic acid by means of melt polymerization. The polymer was identified completely para oriented aromatic polyamide by analytical data. And some information obtained from synthetic process and thermal and/or chemical stability of these polymers was discussed.
