Beschreibung
Zusammenfassung:A water-swelling polymer-mineral composite contains a bentonite clay and a linear polyanionic polymer having a molecular weight of 106 or more, taken in the amount providing a weight ratio of the polymer to the title clay equal to 0.05 - 0.10. The preparation of the composite material is carried out by mixing a bentonite clay and a linear polyanionic polymer having a molecular weight of 106 or more, taken in the amount providing a weight ratio of the polymer to the title clay of 0.05 - 0.10 in the presence of water. Thereafter, the resultant mixture is dried to give the end solid product.
