The invention concerns the field of polymer chemistry and relates to membranes, such as those that can be used, for example, for the preparation of aqueous solutions using microfiltration or ultrafiltration. The object of the present invention is to specify membranes which have improved anti-fouling properties and sliding friction properties. The object is attained with membranes comprised at least predominantly of multiblock copolymers of the general formula (1) where

Membranes for liquid treatment

Water-insoluble anion exchange materials which exhibit improved insolubility in water are used, for example, for anion exchange membranes or as anion exchange resins. The water-insoluble anion exchange materials are at least composed of linearly polymerized and/or branched and/or crosslinked anion exchange groups C, which are part of the structural units according to at least one of the general formulas I to VIII:

The invention relates to the field of polymer chemistry and relates to sulfonated polyarylene compounds such as can be used for example in ion exchange membranes in fuel cells, as well as a method for the production thereof and the use thereof. The object of the present invention is to disclose hydrolytically and thermally resistant sulfonated polyarylene compounds with a defined degree and position of sulfonation, from which membrane materials with an improved resistance to hydrolysis can be produced. The object is attained through sulfonated polyarylene compounds according to at least one of the general formulas (I)-(IV).
