摘要： The present invention concerns fiber made from a polymer comprising imidazole groups, fiber further having: i) a halide anion, the halide anion being present in an amount of 0.05 to 20.1 weight percent, based on weight of fiber; and ii) sulfur, wherein the sulfur is present in the fiber in an amount of 0.05 to 3 weight percent; the fiber exhibiting hydrochloric acid evolution as identified by TGA-IR between 277.13° C. to 448.19° C.
