Abstract:
Disclosed are processes for preparing polyareneazole polymers that include contacting, in polyphosphoric acid, azole-forming monomers and metal powder, the metal powder added in an amount of from about 0.05 to about 0.9 weight percent, based on the total weight of the azole-forming monomers, and reacting the azole-forming monomers to form the polyareneazole polymers. Polyareneazoles, filaments and yarns are also disclosed.
