Modification of Xanthan Gum with Methyl Methacrylate and Investigation of Its Rheological Properties

Xanthan gum modification is considered a significant step in improving shearing, thermal degradation performance, and rheological properties. This paper investigates the rheology properties of grafted copolymer based on xanthan methyl methacrylate (XG-g-MMA), including shear stress viscosity versus rate. The XG-g-MMA was synthesized with different composition ratios (MMA) (1:1.6, 1:5, 1:8 wt.%) presence potassium persulphate initiator. Fourier transform infrared spectroscopy (FTIR) characterized obtained (XG) to confirm grafting process. results analysis show that XG exhibited higher than pure XG. However, increasing MMA ratio increases In addition, measurement showed non-Newtonian thinning behavior for XG-g-MMA. These can further its application fields, such as oil recovery pharmaceuticals.
