摘要： 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, Ar?1 and Ar2¿ represent tetravalent, divalent or trivalent aromatic 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, preferably a branched or unbranched alkyl or alkoxy group, or an aryl group as a further 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 total weight of the polymer containing recurrent azole units, having a particle size smaller than 1 mm.
