In this work, a composite of corn starch grafted (-g-) guar gum was synthesized by a polymerization process using tamarind kernel powder as a polysaccharide. Firstly, grafting was done with corn starch and saponification with alkali, i.e., sodium hydroxide (NaOH). It was further derivatized with tamarind kernel powder through a condensation process and was thermally treated at different temperatures. This leads to some chemical and structural changes in the compound. The characteristics of this composite were studied by 1H NMR (Nuclear Magnetic Resonance), which showed the protonic environment found in the CS-g-GG TKP composite. The FT-IR (Fourier transform infrared spectrum) showed the presence of different functional groups found in the CS-g-GG TKP composite. Scanning electron microscopy (SEM) showed the surface morphology of the composite. Mass spectra showed the molecular weight of the newly synthesized composite.
