Abstract:
PCT No. PCT/EP96/05073 Sec. 371 Date May 20, 1998 Sec. 102(e) Date May 20, 1998 PCT Filed Nov. 18, 1996 PCT Pub. No. WO97/18889 PCT Pub. Date May 29, 1997The 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.
