Abstract

Acrylic acid was grafted onto cellulose acetate using ceric ammonium nitrate (CAN) initiator at varying temperature (30, 40, 50, 60, 70, 80 ˚C) and reaction period of 2-6 hours. Grafting parameters like grafting yield (GY), grafting efficiency (GE) and total conversion of monomer to polymer (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 (FTIR), Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses.
