<p>AROMATIC POLYAMIDE COMPOSITION 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 enchancing agent consisting of one or more inorganic halide, such as alkali metal halides, alkaline earth metal halides and ammonium holides, in amount of from 5 to 60%, based on the weight of the polyamide resin.</p> |
