ABSTRACT:
The present invention provides novel articles of manufacture and a method for absorbing aqueous electrolyte solutions, utilizing polymers formed by crosslinking an ampholytic ion pair (2-methacryloyloxyethyldiethylammonium cation (MEDEA)/sulfonate anion) copolymer. The articles of manufacture of the present invention contain polymers formed by the copolymerization of an effective amount of each of the following components to produce a polymer which is highly absorbent to aqueous electrolyte solutions:
