ABSTRACT:
The invention relates to absorptive, crosslinked polymers which are based on partly neutralized, monoethylenically unsaturated monomer carrying acid groups wherein the absorptive crosslinked polymer may be coated with a thermoplastic polymer, 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 compatibility to affix to a thermoplastic material.
