| titleOfInvention | Cold water-soluble water absorbing material |
| abstract | PURPOSE: To enhance the retentivity of water, blood or excretion in the vicinity of 35°C by preparing a cold water-soluble water absorbing material by freeze-drying a solution of methyl cellulose whose degree of methoxy substitution is 30% or more. n CONSTITUTION: A methyl-etherifying agent such as methyl chloride is added to alkali cellulose obtained by immersing powdery or sheet like cellulose substance in alkali to be reacted with said alkali cellulose in an autoclave and the reaction solution is dried in hot water to prepare a solution of methyl cellulose whose degree of methoxy substitution is 30% or more, pref., 30-44%. Next, this methyl cellulose solution is dissolved in a solvent such as water or benzyl alcohol and the resulting solution is developed and cast on a pallet container having a predetermined size and subsequently free-dried using a usual freeze- melting apparatus to obtain a cold water-soluble water absorbing material. n COPYRIGHT: (C)1990,JPO&Japio |
