Abstract

Partículas de polímero superabsorbente con reticulacion superficial mejorada e hidrofilicidad mejorada, y su uso en artículos absorbentes. Las partículas de polímero superabsorbente de la presente están compuestas por ácido poli(meta)acrílico reticulado y sales de éste. Las cadenas poliméricas comprendidas en las partículas de polímero superabsorbente están reticuladas entre si mediante enlaces covalentes directos y comprenden grupos hidroxilos alcoholicos. Además, un método para la reticulacion superficial de estas partículas de polímero superabsorbente que emplea radiacion ultravioleta de vacío.
