In this paper, the synthesis and characterization of new sulfonated poly(maleimide) is described. Two-step polymerization method was used to prepare the sulfonated poly(maleimide) from maleic anhydride (MA) and p-dimethylamino-azobenzenesulfonic acid (DMBSA). The sulfonation degree of the polymer was regulated through variation of the molar ratio of DMBSA. Flexible, transparent, and mechanically strong membranes were successfully obtained. The membranes were characterized with Fourier transform infrared spectra, 1H NMR, thermogravimetric analysis, ion-exchange capacity, and proton conductivity measurements. These results showed that the membranes had good thermal stability and exhibited high conductivity.
