Title (EN) ABSORBENT STRUCTURES COMPRISING POST-CROSSLINKED WATER-ABSORBENT PARTICLES
(FR) STRUCTURES ABSORBANTES COMPRENANT DES PARTICULES ABSORBANT L'EAU POST-RÉTICULÉES
Abstract: front page image
(EN)Absorbent structures comprising vacuum-treated (optionally coated) post-crosslinked water-absorbing polymeric particles, obtainable by vacuum-treating and optionally plasma-treating post-crosslinked water-absorbent polymeric particles (that may optionally be coated), the resulting vacuum-treated post-crosslinked water-absorbing polymeric particles having an improved absorption, whilst having good gel bed permeability.
(FR)Les structures absorbantes selon l'invention comprennent des particules polymères absorbant l'eau post-réticulées, traitées sous vide (éventuellement, revêtues) qui peuvent être obtenues par traitement sous vide et éventuellement, traitement par plasma de particules polymères absorbant l'eau post-réticulées (qui peuvent éventuellement être revêtues). Les particules polymères absorbant l'eau post-réticulées, traitées sous vide obtenues ont un pouvoir absorbant amélioré, tout en offrant une bonne perméabilité de lits de type gel.
