CATIONIC POLYSACCHARIDES |
摘要 |
A synthesis is described for the preparation of cationic polymer materials with a semisynthetic matrix, having superabsorption characteristics towards water and saline solutions. More particularly, cellulose cationic derivatives are described, having superabsorption characteristics, which are obtained starting from cellulose substrates which are reacted with an excess of a quaternary ammonium compound in an alkaline medium. |
