Using the copper-catalyzed 1, 3-dipolar “click” cycloaddition reaction, poly (sulfone) s containing pendant azide moieties were functionalized with various quantities of sodium 3- (prop-2-ynyloxy) propane-1-sulfonate and crosslinked with 1, 7-octadiyne. The degrees of sulfonation and crosslinking were systematically varied by changing the ratios of the aforementioned reagents. The polymers were cast into membranes, acidified, and then ...
