Synthesis and comparison of hydrogels based on Pistacia atlantica gum

Pistacia atlantica Gum as a polysaccharide has been chemically modified by graft copolymerizationan various monomers in aqueous medium using ammonium persulfate (APS) as an initiator. The results showed that the hydrogels have capacity of swelling significant, and are sensitive to pH. The structure was confirmed by FT-IR and SEM devices.
