In this investigation, superporous hydrogels containing poly(acrylamide-co-methacrylic acid) with interconnected pores were prepared using radical polymerization of methacrylic acid and acrylamide in the presence of N,Nmethylene- bis-acrylamide as crosslinking agent. SPH composite polymers were made using Ac-Di-Sol as a stabilizer. Scanning electron microscopy (SEM), apparent density and swelling ratio studies were used to characterize these polymers. Characterization of the prepared polymers showed that SPH polymers have more pores and higher swelling ratio but less mechanical stability compared to SPH composite polymers, which have less pores and lower swelling ratio but a higher mechanical stability.
