Abstract

Se revelan en la presente solicitud materiales absorbentes útiles en la retención de fluidos corporales tales como orina. En particular, la invención se refiere a composiciones poliméricas absorbentes que tienen excelentes propiedades de funcionamiento de absorbencia en términos de capacidad absorbente bajo una presión restrictiva de 4,8 kPa y/o 9,6 kPa, así como también excelentes propiedades de permeabilidad al fluido. La invención se refiere adicionalmente a elementos absorbentes que comprenden estas composiciones poliméricas absorbentes, y artículos absorbentes que comprenden los elementos absorbentes. Una composición polimérica absorbente que tiene (i) una capacidad de Desempeño Bajo Presión (PUP) en solución de orina sintética bajo una carga aplicada de 4,8 kPa, de por lo menos 39 g/g después de 4 horas; y (ii) un valor de Conductividad de Flujo Salino (SFC) de por lo menos 50 X 10-7 cm3 seg/g aproximadamente. Una composición polimérica absorbente que tiene una capacidad de Desempeño Bajo Presión (PUP) en solución de orina sintética bajo una carga aplicada de 9,6 kPa, de por lo menos 37 g/g después de 16 horas; y (ii) un valor de Conductividad de Flujo Salino de por lo menos 50 X 10-7 cm3 seg/g aproximadamente.<EMI FILE="98077576_1" ID="1" IMF=JPEG >
