Abstract
The paper deals with optimization of the reaction parameters, graft copolymerization, characterizatio n and evaluation of the transformations in Roselle stem fiber on graft copolymerization with vinyl mon omer, using ceric ammonium nitrate nitric acid initiator system.

Different reaction parameters such as temperature, time, initiator concentration, monomer concentration and pH were op timized to get the maximum graft yield. The graft c opolymer thus formed were characterized by advanced techniques.
The physico-chemico-thermal resistance, moisture a bsorbance, swelling behavior of graft copolymers and the dye u ptake behavior were studied and found to have impro ved. Conclusion: Hence, this first report of novel graft copolymer s is to help towards various applications.
