发明名称 Absorbing agents for water and aqueous liquids and process for their production and use
摘要 PCT No. PCT/EP96/03203 Sec. 371 Date Apr. 23, 1998 Sec. 102(e) Date Apr. 23, 1998 PCT Filed Jul. 19, 1996 PCT Pub. No. WO97/06190 PCT Pub. Date Feb. 20, 1997The 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.
