Abstract: | O-(2-Hydroxyethyl), O-(2-hydroxypropyl) and O-carboxymethyl derivatives of guar gum have been prepared under different experimental conditions. Several properties such as moisture regain, rate of hydration, solubility, viscosity and rheology of these derivatives have been studied. The properties depend upon polysaccharide chain length, and the nature and degree of chemical modification. The effect of alkali and alkaline hydrogen peroxide on the properties of guar gum have also been studied. |
