Abstract:
The invention relates to absorptive, crosslinked polymeric composition that are based on partly neutralized, monoethylenically unsaturated monomer carrying acid groups wherein the absorptive crosslinked polymer may be coated with a polymeric coating, and have improved properties, in particular in respect of their capacity for transportation of liquids in the swollen state, and which have a high capacity and a high gel bed permeability.
