The effects of initiator concentration, temperature, duration of reaction, monomer concentration and acid concentration have been studied to obtain the optimum conditions for grafting. The maximum grafting (80%) has been achieved at initiator conc., 0.04 mol/L; monomer conc., 0.45 mol/L; acid conc., 0.2 mol/L; temperature 40°C; and reaction time 2 h). The activation energy of graft copolymerization of HEMA onto jute has been found to be 30 kJ/mol. A suitable mechanism for grafting has also been proposed.</span>
