Abstract :Acrylic acid was grafted onto cellulose acetate using ceric ammonium nitrate insert ignore into journalissuearticles values(CAN); initiator at varying temperature insert ignore into journalissuearticles values(30, 40, 50, 60, 70, 80 ˚C); and reaction period of 2-6 hours. Grafting parameters like grafting yield insert ignore into journalissuearticles values(GY);, grafting efficiency insert ignore into journalissuearticles values(GE); and total conversion of monomer to polymer insert ignore into journalissuearticles values(TC); were evaluated at different reaction conditions such as temperature, time, monomer and initiator concentration. The homopolymer was removed from the reaction mixture using Soxhlet extraction. The graft copolymer of cellulose acetate produced at 70 °C after 3 hours had the highest GY of 85%. The products were characterized by Fourier-transform infrared spectroscopy insert ignore into journalissuearticles values(FTIR);, Scanning electron microscopy insert ignore into journalissuearticles values(SEM); and X-ray diffraction insert ignore into journalissuearticles values(XRD); analyses.
