  "textContent": "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 as having a high glass transition temperature from the hydrophobic end- blocks, low vinyl (rubber) content, and quaternized mid-block. AEMs made from the composition have improved thermal and dimensional stability in electrolyzer operations.",
