ABSTRACT:
Homogeneous polymer alloys comprising, as the main constituents, sulfonated aromatic polyether-ketones and at least one aromatic polysulfone, wherein the materials have a good thermal and mechanical stability and are thereby distinguished in particular as cation exchanger membranes for electrochemical cells with operating temperatures above 100.degree. C.
