Graft copolymerization of acrylic acid onto jute fibers was carried out with quinquivalent vanadium as initiator in an aqueous sulphuric acid medium under nitrogen atmosphere. The graft yield was influenced by reaction time, temperature, concentrations of acid, monomer, initiator, reaction medium, and base polymer. Grafting has also been carried out in presence of various organic solvents. It has been observed that the maximum graft yield 56.7% was obtained at 50°C for [AA] = 1.453 M, [V +5 ] = 15 X 10 −3 M, acid (2.12 M) and for a reaction time of 6 h. The tensile properties, dye‐uptake ability, and absorption of water and water vapours of the grafts have also been studied.
