Preparation of hyperbranched aromatic poly(ethersulfone)s possessing sulfonic acid terminal groups for polymer electrolyte
Hyperbranched poly(ethersulfone) (HPES) having terminal sulfonic acid group was synthesized from 2,6-bis(p-sodium sulfophenoxy)benzonitrile. These films of polymer blend of HPES and polyvinyl alcohol (PVA) exhibited the proton transportation ability.
