Abrégé
(EN)
The invention relates to absorptive, crosslinked polymers which are based on partly neutralized, monoethylenically unsaturated monomers carrying acid groups, and have improved properties, in particular in respect of their capacity for transportation of liquids in the swollen state, and which has a high gel bed permeability and high centrifuge retention capacity.
(FR)
L'invention concerne des polymères réticulés absorbants à base de monomères monoéthyléniquement insaturés partiellement neutralisés, portant des groupes acides, et présentant des propriétés améliorées, en particulier par rapport à leur capacité de transport de liquides en état gonflé, et présentant une perméabilité de lit de gel élevée ainsi qu'une capacité de rétention centrifuge élevée.
