Abstract
Graft copolymers of guar gum (GG) and methylacrylate (MA) were synthes ized by different reaction variables to achieve the optimal reaction c ondition by hydrogen peroxide initiation in aqueous media. The effects of [H2O2], reaction time, [MA] and [GG] on the grafting have been int erpreted in terms of the grafting parameters and of the reactions rate . The products were characterized by infrared spectrophotometry, and t hermogravimetry. The values of the activation energy for the thermal d egradation of the grafted copolymers were found as independent on the extent of grafting.
