The disclosure relates to a metalated-sulfonated styrenic block copolymer (SO3-M+-SBC) composition. The composition is obtained by epoxidation of SBC precursor followed by alcoholysis of epoxidized SBC using Grignard reagent, and then lithiation and sulfon...

The disclosure relates to a hydrogenated styrene-based multiblock copolymer composition, having selectively quaternized midblock, for forming anion-exchange membranes (AEMs). The quaternized hydrogenated styrene-based multiblock copolymer is characterized ...
