摘要：Background and Aim: The paper deals with optimization of the reaction parameters, graft copolymerization, characterization and evaluation of the transformations in Roselle stem fiber on graft copolymerization with vinyl monomer, using ceric ammonium nitrate nitric acid initiator system. Methods: Different reaction parameters such as temperature, time, initiator concentration, monomer concentration and pH were optimized to get the maximum graft yield. The graft copolymer thus formed were characterized by advanced techniques. Results: The physico-chemico-thermal resistance, moisture absorbance, swelling behavior of graft copolymers and the dye uptake behavior were studied and found to have improved. Conclusion: Hence, this first report of novel graft copolymers is to help towards various applications.
