The invention relates to a method for producing a solution consisting of a polymer containing recurrent azole units. A sufficiently dried polymer containing recurrent azole units of general formulae (1) or (2) - wherein radicals Ar, Ar1 and Ar2 represent tetravalent, divalent or trivalent aromat ic or heteroaromatic groups, and radicals X, which are the same inside a recurrent unit, represent an oxygen atom, a sulphur atom, or an amino group having a hydrogen atom and a group comprising 1 to 20 carbon atoms, preferab ly a branched or unbranched alkyl or alkoxy group, or an aryl group as a furthe r radical - is dissolved in N, N-dimethylacetamide having a sufficiently low water content, at a temperature above room temperature, in an inert gas atmosphere. A sufficiently dried polymer containing recurrent azole units of general formulae (1) or (2) is used, up to 90 wt. %, in relation to the tota l weight of the polymer containing recurrent azole units, having a particle si ze smaller than 1 mm. |
