Abstract
Una estructura absorbente que carece de obstrucción capilar (bloqueo de gel) se forma aplicando una o más composiciones precursoras de polímero superabsorbente a un sustrato en una pluralidad de lugares distanciados controlados y determinados previamente, mediante un proceso sin contacto de precisión, haciendo reaccionar químicamente la composición o composiciones precursoras in situ para formar dominios de polímero superabsorbente adheridos al substrato. Los dominios de polímero superabsorbente tienen un tamaño y distanciamiento controlados, de manera que, cuando los dominios de polímero superabsorbente están en un estado completamente hinchado después de la máxima absorción de líquido, los dominios de polímero superabsorbente adyacentes no se tocarán entre sí y no bloquearán los capilares que existen entre los dominios en la estructura absorbente. La estructura absorbente tiene excelente ingreso y distribución de líquido, y una capacidad absorbente óptima. Reivindicación 1: Una estructura absorbente de alto rendimiento que incluye superabsorbente agregado a un substrato a través de polimerización in situ caracterizada porque comprende: un substrato, y una multiplicidad de dominios de polímero superabsorbente formados in situ sobre el substrato o en él, y unidos al substrato; los dominios de polímero superabsorbente que tienen un diámetro de dominio no hinchado promedio Dno hinchado, y una desviación estándar de diámetro de dominio no hinchado de 10% o menos; los dominios de polímero superabsorbente tienen un distanciamiento no hinchado promedio S definido por medio de la siguiente ecuación: en la cual K es por lo menos 1,05; As es la absorbencia máxima del superabsorbente, expresada en gramos de líquido acuoso absorbido por gramo de superabsorbente, rS es la densidad del superabsorbente en el estado no hinchado seco; y rL es la densidad del líquido acuoso que se absorbe.
