| Abstract: | The effect of reaction conditions on the grafting parameter during grafting of acrylamide onto guar gum has been studied using peroxydiphosphate–metabisulphite redox pair at 35 °C. Grafting ratio, efficiency and add‐on all increase as the concentrations of peroxydiphosphate and acrylamide increase up to 40.0 × 10?3 mol dm?3 and 40.0 × 10?2 mol dm?3, respectively. It has been observed that the optimum concentrations of metabisulphite and guar gum for obtaining high grafting ratio, efficiency, add‐on and conversion are 6.0 × 10?3mol dm?3 and 91.7 × 10?2 g dm?3, respectively. © 2000 Society of Chemical Industry |
