An aromatic polyamide composition usable for producing shaped articles, for instance, filaments, comprises the components of an aromatic polyamide resin (P), a polar amide solvent (S) and an auxiliary solvent (H) consisting of a halogenated hydrocarbon, for example, dichloromethane and dichloroethane, the proportions of the components (P), (S) and (H) being on or within a quadrilateral A C D E defined by the co-ordinates: A (P 5.0, S 30.0, H 65.0 ) C (P 45.0, S 30.0, H 25.0) D (P 57.0, S 38.0, H 5.0) and F (P 5.0, S 90.0, H 5.0). The composition also contains a solubility enhancing agent consisting of one or more inorganic halide, such as alkali metal halides, alkaline earth metal halides and ammonium halides, in amount of from 5 to 60%, based on the weight of the polyamide resin. |
