Abstract

La invención se refiere a polímeros hidrófobos, con alta capacidad de hinchamiento para fluidos acuosos, por ejemplo superabsorbentes, que se recubren con polímeros reactivos, insolubles en agua, filmógenos e hidrófobos y un constituyente reactivo adicional que puede reaccionar con grupos carboxilos o aniones carboxilato y que forma reticulación adicional sobre la superficie de las partículas. La invención se refiere también a la producción de un superabsorbente recubierto de esta manera y a su utilización en artículos higiénicos que se utilizan para la absorción de fluidos corporales. Los productos obtenidos recubriendo polímeros con alta capacidad de hinchamiento, hidrófilos e insolubles con polímeros reactivos, insolubles en agua, filmógenos e hidrófobos y un componente reactivo adicional se caracterizan porque se puede ajustar su velocidad de absorción de manera controlada en un área extensa según el tipo y cantidad utilizada de polímeros reactivos, insolubles en agua, filmógenos e hidrófobos para recubrir y según las condiciones tecnológicas elegidas para efectuar dicho recubrimiento.
