    摘要: A sulfonated aromatic perfluorocyclobutane block copolymer comprises a hydrophobic perfluorocyclobutane ether chain segment and a hydrophilic sulfonated perfluorocyclobutane ether chain segment. The sulfonated perfluorocyclobutane copolymer may be used to make proton conductive membranes and membrane electrode assemblies in fuel cells. Processes of making the block copolymer through thermal coupling reactions are also disclosed.
