Abstract
PURPOSE: An optically isotropic aromatic polyamide dope prepared by dissolving a specific para-oriented aromatic polyamide in a N-substituted amide solvent incorporated with lithium bromide and/or calcium bromide.
CONSTITUTION: (A) An aromatic polyamide having repeating units, preferably of formula II, expressed by formula I: (X and Y are 1W3C alkyl, 1W3C alkoxy, nitro, cyano groups, or halogens; n and m are integers 0W4, however, are not 0 at the same time) as main structural units is dissolved in (B) a N-substituted amide solvent, e.g. N,N-dimethylacetamide or N-methyl-2-pyrrolidone, having a boiling point of about 250°C or below incorporated with (C) lithium bromide and/ or calcium bromide. Preferably, the polymer (A) has an intrinsic viscosty of about 0.3W11 (measured by using a 0.5 g/100 ml solution in cone. sulfuric acid at 30°), and its concentration is about 1W70 wt.% based on the total dope. The amount of components (C) is preferably about 10W200 wt.% based on the polymer weight.
