Abstract

The present invention relates to powdery, water- swellable, cross linked polymers having ‎a high absorption, capacity for aqueous liquids, in particular body fluids, under load, ‎which polymers are formed of a)‎ ‎55-99.9% acid groups containing monomers which are neutralized to the extent of ‎at least 50 mole- %‎ b)‎ ‎0.40% wt of monomers which are copolymerizable with a)‎ c)‎ ‎0.1-5%wt of at least one cross – linking agent‎ d)‎ ‎0.30% wt of a water soluble polymer‎ The captions of the salts according to a) are Li+ Na+ preferably K+, Cs+ , Rb+ , as well ‎as primary , secondary and tertiary methyl ammonium ions, either alone or in ‎combination, the polymers are manufactured in that a blowing agent based on carbon ‎dioxide is added to the monomers, followed by polymerization, that the polymer is dried ‎and then heated to a temperature of 100-300c with one or several compounds which are ‎reactive for surface cross linkage, theses polymers are suitable as component in sanitary ‎articles which absorb body fluids and in wound dressings, as component in diapers, ‎sanitary napkins, and incontinence articles, as component in current- conducting and ‎light-transmitting cable, as soil conditioner, artificial soil for plant breeding , and as ‎component in packaging materials.‎
