Absorbent polymer material based on renewable starting materials |
摘要 |
A method of production of a highly absorbent, polysaccharide-based material, wherein an aqueous solution containing a starting material including a cross-linkable polysaccharide-based polymer blend of an electrically charged polysaccharide-based polymer and an electrically uncharged polysaccharide-based polymer is subjected to cross-linking in order to obtain a water-swelled gel. The cross-linked, water-swelled gel is dessicated with a polar solvent.
