    摘要: The present invention relates to a powdery, cross-linked polymer absorbing water and aqueous liquids formed of polymerized, unsaturated, acid groups-containing monomers that are present as salts neutralized to the extent of at least 50 mol-% and which optionally comprise further monomers which are copolymerizable with the acid groups-containing monomers as well as water-soluble polymers, the polymer being formed of acidic, polymerized monomers partially neutralized to the extent of 5-30 mol-%, relative to the acid groups-containing monomer portion. The polymer has a high retention, high liquid absorption under pressure, high swelling pressure, and a low content of soluble components. The present invention further relates to a process for the production of said polymer and to its use as a component in sanitary articles which absorb body fluids and in wound dressings, in current-conducting and light-transmitting cables, as soil conditioners, as a component in packaging materials and in depot materials for the controlled release of active substances.

    摘要: The present invention relates to cross-linked polymers absorbing aqueous liquids, which are built up of partially neutralized, mono-ethylenically unsaturated, acid groups-containing monomers, optionally further monomers copolymerizable with these, as well as optional polymers suitable as a graft basis, and that can be produced by using cross-linking agents of polyunsaturated amino alcohols. The used cross-linking agents are reaction products of (meth)allylamines with monoglycidyl compounds, di-, tri- or tetraglycidyl compounds, and optional alkylene oxide; reaction products of (meth)allylamines or saturated primary amines with (meth)acrylglycide esters and/or (meth)allyl glycidyl ethers and optional alkylene oxide; as well as reaction products of di- and polyamides with (meth)allyl glycide esters and/or (meth)acrylglycide esters and optional alkylene oxide. The polymers according to the present invention provide superabsorbers whose property level meets the practice-oriented requirements with respect to retention, absorption under pressure, swelling pressure, and permeability for aqueous liquids. Such polymers are used as absorbents for water and aqueous liquids in constructions for the absorption or body fluids, in current-conducting and light-transmitting cables, and in the cultivation of plants.
