Abstract

Materiales de polímero superabsorbente que incluye polímeros absorbentes que tienen un tiempo de vórtice rápido, deseablemente de alrededor de 10 segundos o menos, y un índice de rigidez de por lo menos alrededor de 0,7, como se determinó por los procedimientos de prueba descriptos aquí. Los polímeros absorbentes pueden ser modificados para obtener un tiempo de vórtice más rápido por un método que incluye proporcionar un polímero absorbente que tiene un primer tiempo de vórtice, absorber el agua con el polímero absorbente, secar por congelación el polímero absorbente hinchado para remover por lo menos una parte del agua absorbida, y obtener un polímero absorbente modificado que tiene un segundo tiempo de vórtice. La proporción del primer tiempo de vórtice al segundo tiempo de vórtice es de por lo menos alrededor de 5, y deseablemente el polímero absorbente modificado tiene un índice de rigidez de por lo menos alrededor de 0,7.
