摘要：
Cotton linters is irradiated by Co-60 source with different doses (5 ... 52 Mrad). The effect of gamma-irradiation on the grafting of cotton linters with methylmethacrylate monomer (MMA) is clarified, crystallinity index (CrI) of irradiated samples decreases by increasing the radiation dose. A new hand appeared at 1715 cm-1 (C = O) after irradiation. On the other hand, band intensities of some groups at 1600 cm-1 (RCOO) are increased or decreased, e.g. OH at 3350 cm-1 by irradiation.
