Microcrystalline cellulose-graft-Acrylamide (MCC-g-AM) was synthesized by ,60,Co γ-rays pre-irradiation method. The effects of various reaction conditions on the grafting degree and the utilization ratio of acrylamide were studied. The structures of the grafted copolymers were characterized by Fourier transform infrared spectroscopy (FT-IR). The highest grafting degree and utilization ratio of acrylamide were more than 65%, which was obtained at reaction time of 3 h, pre-absorbed dose of 35 kGy, reaction temperature of 40℃, MCC/AM mass ratio of 0.5:1, Fe(NH,4,),2,(SO,4,),2,·6H,2,O/AM mass ratio of 0.01%, and AM monomer concentration of 5%.
