METHOD OF PREPARING WATER INSOLUBLE CRAFTED COPOLYMERS ADSORBING AQUEOUS LIQUIDS |
| 摘要 |
Absorbent polymeric compositions are prepared by graft polymerizing acrylonitrile onto flour or other starch-containing substrates and then subjecting the flour-polyacrylonitrile graft copolymers to alkaline saponification. Compositions prepared from gelatinized flour absorb from 1800-3000 times their weight of deionized water. |
