The present paper reports the modification of guar gum through the grafting of 2-acrylamidoglycolic acid by free radical polymerization using an efficient potassium peroxydiphosphate/thioacetamide redox system in nitrogen atmosphere. The reaction conditions for maximum grafting have been optimized by varying the reaction variables including the concentration of 2-acrylamidoglycolic acid (5.3×10-2 mol dm-3), potassium peroxydiphosphate (1.2×10-2 mol dm-3), thioacetamide (TA) (2×10-3 mol dm-3), sulphuric acid (4×10-3 mol dm-3), guar gum (1 g dm−3) along with time duration (150 min) and temperature (35°C). Water swelling capacity and flocculation and studies of synthesized graft copolymer have been performed with respect to the parent polymer. The graft copolymer has been characterized by Fourier transform infrared spectroscopy and thermogravimetric analysis.
