| Abstract: | Polymer hydrogel based on sodium 2-acrylamido-2-methylpropansulfonate, covalently crosslinked with N,N′-methylenebisacrylamide has been shown to degrade in aqueous ascorbic acid. The hydrogel degradation is induced by chemical interaction of the polymer crosslink and an ascorbic acid oxidation intermediate. |
