Abstract

La presente invención se refiere a materiales de espumasabsorbentes desplomadas de baja densidad que al entrar en contacto con fluidos acuosos, en particular orina, pueden expandirse y absorber estos fluidos, estas espumas de baja densidad tienen típicamente un espesor expandido de 6 a 10 veces, aproximadamente, espesor de las espumas en su estado desplomado. Tambien se refiere a un proceso para la preparación de un material de espuma polimerico absorbente que comprende los pasos de:Formar una emulsión de agua en aceite; polimerizar el componente monómero de las fase oleosa de la emulsión de agua en aceite para formar un material de espuma polimerica.
