Abstract

La presente invención se refiere a una composición polimérica superabsorbente, para absorber y retener fluidos acuosos, esta composición comprende un copolímero substancialmente insoluble en agua, polimerizado de un monómero que incluye al menos un primer monómero hidrofílico, seleccionado del ácido acrílico y las sales solubles en agua del ácido acrílico, y una cantidad de al menos un segundo monómero hidrofílico, efectiva para al menos reducir la extensión de la separación de fase de la mezcla de reacción, la cual ocurriría brevemente después de comenzar la polimerización en la ausencia de al menos un segundo monómero hidrofílico.
