Abstract

La presente invención se refiere a artículos absorbentes que incluyen composiciones absorbentes las cuales exhiben un comportamiento de hinchado, deshinchado y de volver a hinchar. Más específicamente, las composiciones absorbentes de esta invención se hinchan y absorben los fluidos después de la exposición a los fluidos acuosos, se deshinchan y liberan fluidos desde las composiciones absorbentes hinchadas, y también pueden volverse a hinchar y absorber fluidos. El comportamiento de hinchado-deshinchado-volver a hinchar permite una distribución de líquido mejorada en los compuestos absorbentes y en los artículos absorbentes.
