COMPOSITION CONTAINING POLYAZOLE

摘要

Disclosed is a composition in the form of a solution and/or dispersion, comprising at least one polyazole that has an intrinsic viscosity ranging from 3.0 to 8.0 g/dL, the viscosity being measured in at least 96 percent by weight of sulfuric acid, and orthophosphoric acid (H3PO4) and/or polyphosphoric acid. Said composition is characterized in that the polyazole content ranges from 0.5 to 30.0 percent by weight relative to the total weight of the composition, the H3PO4 and/or polyphosphoric acid content ranges from 30.0 to 99.5 percent by weight relative to the total weight of the composition, and the concentration of the H3PO4 and/or the polyphosphoric acid, calculated as P2O5 (acidimetrically), ranges from 70.5 to 75.45 percent relative to the total amount of H3PO4 and/or polyphosphoric acid and/or water. Particularly suitable methods for producing and using the composition of the invention are also claimed.
