Abstract: The present invention relates to a process for preparing aqueous formulations (A) comprising at least one polyaromatic compound bearing acid groups, in particular a sulfonated polyaromatic compound, and also aqueous formulations (A) which have been prepared by the process of the invention. Furthermore, the present invention relates to a process for preparing dried formulations (B) by removing the water from the aqueous formulations (A) and also the dried formulations (B) themselves. The present invention further provides a formulation (C) comprising the dried formulation (B) of the invention and water or the formulation A of the invention and a water-comprising formulation (D) comprising the aqueous formulation (A) or the formulation (C) of the invention and additionally at least 2% by weight of an organic solvent. Furthermore, the present invention relates to dry formulations (E) which are obtained by removing water and solvent from the water-comprising formulations (D) of the invention. The present invention further provides for the use of the water-comprising formulations (D) of the invention and of the dry formulations (E) obtained from these for producing a polymer electrolyte membrane and also the polymer electrolyte membrane itself and a membrane-electrode assembly (MEA) and also a fuel cell comprising the polymer electrolyte membrane of the invention.
