    • There is provided an aromatic polyamide composition, which comprises (a) a polyamide, the recurring structural units of which are substantially totally aromatic, (b) an organic amide solvent, and (c) one or more salts selected from chlorides and bromides of an alkali metal, an alkaline earth metal or ammonium. The amounts of the polyamide and the organic amide solvent are in the ranges of 30 to 50% and 70 to 50% by weight, respectively, based on the total weight of the polyamide and the organic amide solvent. The amount of the salt is defined by the formulae:in the case where 30.ltoreq.x.ltoreq.33.6, y.gtoreq.10, andin the case where 33.6 2.8x-84wherein "x" is the amount in % by weight of the polyamide based on the total weight of the polyamide and the organic amide solvent, and "y" is the amount in % by mole of the salt based on the polyamide. The polyamide composition is useful for melt-shaping films, fibers and other shaped articles.
