Herein, we report the synthesis of proton-conducting sulfonated poly­(ionic liquid) block copolymers (S-PILBCPs) containing one block with sulfonic acid (sulfonated styrene, SS) and the other with an IL moiety (vinylbenzylmethylimidazolium bis­(trifluoromethylsulfonyl)­imide, VBMIm-TFSI) using rever...
