Ion-sensitive, water-dispersible polymers, a method of making same and items using same |
摘要 |
A method of making an ion-sensitive composition is disclosed. The method of the present invention comprises dispersing in a sulfonate anion modified acrylic acid-based polymer a non-crosslinking poly(ethylene-vinyl acetate). The ion sensitive compositions made by the method of the present invention have differing solubilities in neutral salt solutions containing at least about 1 weight percent of one or more monovalent salt ions and water containing up to about 200 ppm of one or more multivalent ions.
