Abstract

Se describe un polimero superabsorbente de color estable que tiene una estabilidad de color a largo plazo, y metodos de fabricacion del polimero. El polimero superabsorbente se prepara utilizando un derivado del acido sulfinico, similar al acido 2-hidroxi-2-sulfinatoacetico, una sal de este, o una mezcla de ellos, como el agente reductor en un sistema iniciador de polimerizacion para la preparacion de un polimero superabsorbente de monomeros. El polimero superabsorbente resultante resiste la degradacion de color durante los periodos extendidos de almacenamiento, incluso a una elevada temperatura y humedad.
