Abstract
La presente invencion se relaciona con particulas de polimeros superabsorbentes con reticulacion de superficie mejorada y con su uso en articulos absorbentes. Las particulas de polimero superabsorbente de la presente invencion comprenden una resina hidroabsorbente y el producto de reaccion de un reticulador de superficie activable por radiacion, en donde el producto de reaccion del reticulador de superficie activable por radiacion esta presente sobre las superficies de las particulas de polimero superabsorbente. El agente de reticulacion superficial activable con radiacion comprende por lo menos dos grupos R activables con radiacion, los cuales estan unidos covalentemente uno a otro o a por lo menos un grupo espaciador S. Por otra parte, la invencion se relaciona con un proceso para elaborar estas particulas de polimeros superabsorbentes.
