olyaniline (PANI) with various inherent viscosities have been synthesize under a number of different reaction conditions. Their solubilities in organic solventshave been studied. It was found that the best solvent for PANt isN-methylpyrrolidone (NMP ) and only low molucular weight PANt can be dissolved in organic solvents. Soluble PANt ([η] =0. 49dl/g) in NMP was used tocopolymerize with -COCI terminated low molecular weight poly-(p- phenylene terephathalamide). Through elemental analysis the molecular weight of PANi has been ascertained.
