Patent ID: 8722279

Claim:
A 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 dl/g, and orthophosphoric acid 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 3 PO 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 3 PO 4 and/or polyphosphoric acid concentration, calculated as P 2 O 5 (by acidimetric means), based on the total amount of H 3 PO 4 and/or polyphosphoric acid and/or water, is in the range from 70.5% to 75.45%.
