Block copolymer, method for producing a block copolymer, membrane, use of a membrane, and method for producing a membrane

Abstract

The present invention relates to a block copolymer comprising at least two different polymer blocks, wherein one polymer block consists at least predominantly of a first, ion-conducting polymer, wherein the ion-conducting polymer has ion-conducting functional groups, and one polymer block consists at least predominantly of a second, mechanically flexible polymer, wherein the mechanically flexible polymer has a lower glass transition temperature than the ion-conducting polymer, as well as a process for producing a block copolymer, a membrane and the use of a membrane.
