    • 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.
    • 本发明涉及一种制备水性制剂(A)的方法,该制剂包含至少一种带有酸基的多芳族化合物,特别是磺化多芳族化合物,以及通过本发明方法制备的水性制剂(A)。 此外,本发明涉及通过从水性制剂(A)中除去水以及干燥制剂(B)本身来制备干燥制剂(B)的方法。 本发明还提供了包含本发明的干燥制剂(B)和水或本发明的制剂A的含水制剂(D)的制剂(C)和包含水性制剂(A)或制剂(C )和另外至少2重量%的有机溶剂。 此外,本发明涉及通过从本发明的含水制剂(D)中除去水和溶剂而获得的干燥制剂(E)。 本发明还提供了本发明的含水制剂(D)和由它们获得的干燥制剂(E)用于制备聚合物电解质膜的用途,以及聚合物电解质膜本身和膜 - 电极组件 (MEA)以及包含本发明的高分子电解质膜的燃料电池。
