| titleOfInvention | Method for removing sulfur from fibers using halo acid ion exchange |
| abstract | The present invention relates to a method for removing sulfur from fibers made of polymers containing imidazole groups, the method comprising: a) combining undried sulfate anion-containing polymer fibers with halogen-containing acid contacting the ions to replace at least a portion of the sulfate ions with halide anions; and b) washing the fibers to remove the displaced sulfate ions. |
