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 dfined 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.
一种芳香族聚酰胺组合物可用于生产异型制品,例如长丝,其组分包括芳香族聚酰胺树脂 (P)、极性酰胺溶剂 (S) 和由卤代烃,例如二氯甲烷和二氯乙烷组成的辅助溶剂 (H),组分 (P)、(S) 和 (H) 的比例在由坐标确定的四边形 A C D E 上或范围内:
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)和
F(P 5.0,S 90.0,H 5.0)。
组合物中还含有一种溶解度增强剂,由一种或多种无机卤化物组成,如碱金属卤化物、碱土金属卤化物和铵卤化物,用量为聚酰胺树脂重量的 5%至 60%。
