| 中文摘要 | radiation crosslinking of carboxymethylcellulose (cmc) with a degree of substitution (ds) from 0.7 to 2.2 was the subject of the current investigation. cmc was irradiated in solid-state and aqueous solutions at various irradiation doses. the ds and the concentration of the aqueous solution had a remarkable affect on the crosslinking of cmc. irradiation of cmc, even with a high ds, 2.2 in solid state, and a low ds, 0.7 in 10% aqueous solution, resulted in degradation. however, it was found that irradiation of cmc with a relatively high ds, 1.32, led to crosslinking in a 5% aqueous solution, and 20% cmc gave the highest gel fraction. cmc with a ds of 2.2 induced higher crosslinking than that with a ds of 1.32 at lower doses with the same concentration. hence, it was apparent that a high ds and a high concentration in an aqueous solution were favorable for high crosslinking of cmc. it is assumed that; high radiation crosslinking of cmc was induced by the increased mobility of its molecules in water and by the formation of cmc radicals from the abstraction of h atoms from macromolecules in the intermediate products of water radiolysis. a preliminary biodegradation study confirmed that crosslinked cmc hydrogel can be digested by a cellulase enzyme.
