Roselle is rich in cellulose conten

Roselle is rich in cellulose content and exists as waste bio-mass in abundance thorough-out the world. It has low weight and high tensile strength that promotes its use as backbone for graft copolymerization. Various reaction parameters for the graft copolymerization of effective acrylate monomer onto stem fiber were optimized and used in binary mixture with six vinyl monomers to screen the change in properties of the fiber. These graft copolymers were characterized by advanced analytical techniques and evaluated for mechanical strength after being incorporated in polymer matrix based composite as reinforcement.Graft copolymerization of butyl acrylate and its binary vinyl monomeric mixtures onto Roselle fiber increased the chemical resistance and decreased the %Cr and C.I. of the fiber. However, the cellulose form I remained unchanged after graft copolymerization, under the optimized reaction conditions. The use of these graft copolymers in phenoplast as reinforcement increased the chemical resistance and mechanical strength. These noble materials procured from renewable waste bio-mass could be used in insulator, transportation, packaging and aerospace for better scientific application and advancement of technology.
