Abstract

Partículas de polímero superabsorbente con reticulación superficial mejorada y su uso en artículos absorbentes. Las partículas de polímero superabsorbente comprenden una resina absorbente de agua y el producto de reacción de un agente de reticulación superficial activable con radiación en donde el producto de reacción del agente de reticulación superficial activable con radiación está presente en las superficies de las partículas de polímero superabsorbente. El agente de reticulación superficial activable con radiación comprende por lo menos dos grupos activables con radiación R, los cuales están unidos covalentemente uno al otro o a por lo menos un grupo espaciador S. Además, un proceso para fabricar estas partículas de polímero superabsorbente.
