摘要
A process for preparing shaped articles of manufacture such as fibers, films and coatings from aromatic polyamide anions in liquid sulfoxides; anisotropic solutions of aromatic polyamide anions useful for the preparation of shaped articles having anistropic properties; isotropic solutions comprising the potassium salt of the polyamide anion; and methods for regulating solution viscosity by control of the degree to which the aromatic polyamide anions are deprotonated.
