Ethyl methacrylate was grafted onto delignified Grewia optiva fiber using ascorbicacid/H2O2 as redox initiators in an aqueous medium. The reaction variables includingconcentration of ascorbic acid, H2O2, monomer and amount of backbone as well as time andtemperature have been varied for establishing grafting. The influence of these reactionconditions on the grafting yield has been discussed. The overall activation energy of grafting hasbeen calculated. The FT-IR spectroscopy, Thermal Gravimetric Analysis (TGA) and ScanningElectron Microscopic (SEM) techniques have been used for the characterization of graft copolymer.
