ABSTRACT:
Disclosed herein are chromium carbonyl complexes of polyamides containing units derived from aromatic diamines in which about 10 to about 90% of those units are complexed with a chromium carbonyl compound, and a process for making them. When aramids are used, the solubility of the polymer in organic solvents is enhanced, and in the case of certain aramids lyotropic solutions are formed. These solutions can be used to make anisotropic films and fibers.
