RADIATION-INDUCED GRAFT POLYMERIZATION ON TO CELLULOSE (in Japanese)
Dry-state grafting was attempted by means of pretreatment of cellulose before irradiation. Unbleached cotton bleached cotton, and rayon fiber, chosen as the backbone polymers, were boiled with water, and then the water was substituted with methanol, ethanol, or propanol by boiling at their boiling point. Before the water was replaced by butanol, octanol, acetone, methyl ethylketone, or ethyl acetate by heating at 100 deg C, the replacement of water by methanol was necessary because of their poor hydrophilic character. Finally, the sample was dried completely in vacuo at 55 deg C. The grafting was performed by both simultaneous and post-irradiation, the dose rate of gamma rays from Co-60 was 4.0 x 10/sup 4/ r/hr, and the total dose was 4.5 Mr. (JAIF)
