Absorbent polymeric compositions derived from amylaceous material-formaldehyde substrates |
| abstract |
Absorbent polymeric compositions are disclosed which are prepared by graft copolymerizing acrylonitrile onto an amylaceous material-formaldehyde substrate and then subjecting the graft copolymer to alkaline saponification. The resulting absorbent polymeric composition sets up into a hard gel after absorbing multiple weights (e.g., up to about 3,000 times its own weight) of water. |
