    • Disclosed is a method for producing a polyazole that has an inherent viscosity of more than 2.9 dL/g, measured in at least 96 percent by weight of sulfuric acid at 25°C. Said method comprises the steps of i) mixing one or more aromatic tetra-amino compounds with one or more aromatic carboxylic acids or the esters thereof, which contain at least two acid groups per carboxylic acid monomer, or mixing one or more aromatic and/or heteroaromatic diamino carboxylic acids, in polyphosphoric acid in order to obtain a solution and/or dispersion, ii) heating the mixture from step i) in inert gas to temperatures ranging from 120 to 350°C in order to obtain the polyazole. The mixture heated in step ii) has a polyphosphoric acid concentration, calculated as P2O5 (acidimetrically), of more than 78.22 percent relative to the total amount of H3PO4, polyphosphoric acid, and water in the mixture. Furthermore, the amounts of the components are selected in such a way in step i) that in step ii), the weight ratio of the tetra-amino compounds and the aromatic carboxylic acids or the esters thereof, which contain at least two acid groups per carboxylic acid monomer, or the diamino carboxylic acids of the mixture is less than 11.0 percent by weight relative to the total weight of the mixture. The reaction mixture is heated to a temperature exceeding 220°C in step ii).
