摘要

A new type of ion exchange polymer, bis [(perfluoroalkyl) sulfonyl] imide ionomers (PFSI), were developed by the copolymerization of sodium 3, 6-dioxa-Δ7-4-trifluoromethyl perfluorooctyl trifluoromethyl sulfonimide with tetrafluoroethylene (TFE) using an aqueous redox initiation system in an emulsion type polymerization. These polymers have been prepared in various equivalent weights and processed into functional membranes. The ...
