AbstractA novel hydrogel has been synthesized by grafting methacrylic acid (MAA) onto Gum arabic (GA) through free radical graft co-polymerization in the presence of potassium persulphate (KPS) as an initiator and hexamethylene tetramine (HMTA) as a cross-linker. Various reaction parameters like reaction temperature, reaction time, concentration of initiator, amount of solvent, pH, concentration of monomer and concentration of cross-linker were optimized. GAcl-poly(MAA) was characterized by FTIR spectroscopy, SEM and TGA-DTA techniques. Optimized polymer was studied for its salt-resistant swelling behavior in different solutions: NaCl, MgCl2, CaCl2, FeCl3, ZnCl2 and BaCl2 as a function of salt concentration, temperature and pH. It was observed that GA-cl-poly(MAA) exhibits following salt-resistant swelling trend in different salts: NaCl > ZnCl2 > MgCl2 > CaCl2 > BaCl2 > FeCl3
