BIODEGRADABLE WATER-ABSORBING MATERIAL, ITS PRODUCTION METHOD, AND COMPOSTING AID COMPRISING THE MATERIAL |
摘要 |
PROBLEM TO BE SOLVED: To provide a biodegradable water-absorbing material which is excellent in biodegradability, inexpensive, good in water absorption and also has a high heat-resistance at a swollen state and water retainability at a high temperature and can be used as a suitable composting aid. SOLUTION: The biodegradable water-absorbing material is characterized in that the material is prepared by introducing hydrophilic groups to starch lees containing 26-90 mass% starch in terms of dry mass and subjecting the resultant material to crosslinking. Starch lees being low in utility value can be used effectively. COPYRIGHT: (C)2007,JPO&INPIT
