Series of novel hydrogels based on sodium styrene sulfonate(SSNa) and tetraethylene glycol dimethacrylate (TeEGDMA) copolymers, were prepared by free radical cross-linking copolymerization and were characterized using Spectra of Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC).The swelling properties of these hydrogels were achieved in distilled water at different pH at 25°C, the results showed that the swelling ratio are proportional to the sodium styrene sulfonate(SSNa) percent molar composition of 40, 50 and 80 incorporated in each hydrogel, The values swelling ratio of the basic medium are higher than those observed in acidic and neutral medium.
