(abstract)

Sulfonation of PPSU is accomplished by aromatic nucleophilic substitution reactions, introducing a sulfonyl group into the electron-rich biphenyl group. Since the performance of the ion exchange resin depends on the ion exchange capacity of the polymer, sulfonation was performed by changing the acid type in order to introduce more sulfonyl groups into PPSU. Although the ion exchange capacity can be increased by changing the acid type and temperature conditions, the optimum conditions are required because degradation of the polymer structure also occurs at the same time. We report on the synthesis and properties of sulfonated PPSU to get best performance.
