Abstract
Una estructura absorbente que contiene un superabsorbente que ha sido producido a partir de 1 o más monómeros hidrofílicos por copolimerización de radical libre en la presencia de almidón y/o almidón modificado químicamente, caracterizado en que se ha hecho uso, durante la producción del superabsorbente, de un iniciador de radical libre que forma 3 o más sitios radicales por molécula, y en que la estructura absorbente (1, 3) incluye fibras hidrofílicas y/o hidrofóbicas que, juntas con el absorbente imparten un carácter hidrofílico a la estructura absorbente, y en que, en el estado seco, el superabsorbente constituye entre el 10 al 75% del peso seco de la estructura absorbente. <EMI FILE="99016185_1" ID="1" IMF=JPEG >
