抄録

A novel series of poly(arylene ether sulfone ketone) multiblock copolymers containing sulfonic acid and bromine groups in the hydrophilic blocks were synthesized and characterized. The copolymers were high molecular weight (Mn = 21-98kDa, Mw = 234-357kDa) and provided bendable and transparent membranes by solution casting. The bromine groups caused slight decrease in the proton conductivity at low humidity, however, were effective in improving the mechanical properties as confirmed by dynamic mechanical analyses and tensile tests.
