Process for making membranes

Process for making a membrane M comprising the following steps: a) preparing a copolymer C, wherein said copolymer C comprises blocks of at least one polyarylene ether A and blocks of polyalkylene oxide PAO, wherein the content of polyethyleneoxide in copolymer C is 30 to 90% by weight and wherein c...
