Popis:	Graft copolymerization of methyl methacrylate (MMA) onto wool fibers has been carried out in an aqueous medium under deaerated condition initiated by potassium monopersulphate (KHSO5/Fe(III) system, at varying concentration of the reactants and temperature. The effect of various salts and organic solvents on the extent of grafting has also been studied. Maximum graft percentage of 210.8% was obtained in 4 h at 40°C with the concentration of MMA (0.46 M), KHSO5 (0.0195 M), Fe(III) (1.25 × 10−4M) in the presence of 50% formic acid. Various improved properties of the grafts have been studied and compared with the parent fiber.
