Grafting of methyl methacrylate onto guar gum by hydrogen peroxide initiation

摘要

AbstractGraft copolymerization of methyl methacrylate (MMA) onto guar gum (GG) in aqueous slurry has been carried out using hydrogen peroxide (H2O2) as initiator. The copolymers were characterized by infrared spectroscopy. The grafting parameters like percent grafting, grafting efficiency, percent add‐on, and the grafting frequency were determined, and the effect of reaction time, concentration of initiator, and GG/MMAratios on the grafting parameters have been discussed. The decrease in add‐on at increasing concentration of H2O2indicated enhancement in the rate of homopolymerization of methyl methacryl
