Title: Polyazole-containing composition

Abstract: Composition in the form of a solution and/or dispersion, comprising: at least one polyazole with an intrinsic viscosity, measured in at least 96% by weight sulfuric acid, in the range from 3.0 to 8.0 g/dl, and orthophosphoric acid (H.sub.3PO.sub.4) and/or polyphosphoric acid, wherein the polyazole content, based on the total weight of the composition, is in the range from 0.5% by weight to 30.0% by weight, the H.sub.3PO.sub.4 and/or polyphosphoric acid content, based on the total weight of the composition, is in the range from 30.0% by weight to 99.5% by weight, the H.sub.3PO.sub.4 and/or polyphosphoric acid concentration, calculated as P.sub.2O.sub.5 (by acidimetric means), based on the total amount of H.sub.3PO.sub.4 and/or polyphosphoric acid and/or water, is in the range from 70.5% to 75.45%. Additionally protected are particularly advantageous processes for preparation and for use of the inventive composition.
