Abstract

Nitroxide-mediated polymerization enabled the synthesis of cationic, imidazolium-containing triblock copolymers as a membrane for an electromechanical transducer. Nitroxide- mediated polymerization afforded poly (styrene-b-[1-ethyl-3-(4-vinylbenzyl) imidazolium bis (trifluoromethane sulfonyl) imide)]-b-styrene) in a controlled fashion as confirmed using aqueous size exclusion chromatography and 1H NMR spectroscopy. Dynamic ...
