| titleOfInvention | process for producing a water-absorbing polymer composition, composite, process for producing a composite and using the water-absorbing polymer composition or a composite |
| abstract | process for producing a composition of water-absorbing polymers, composite, process for producing a composite, foams, molds, fibers, sheets, films, cables, sealing materials, liquid-absorbent hygiene articles, plant growth carriers and fungi growth regulators, packaging materials, soil additives or construction materials and use of water-absorbing polymer or a composite the invention relates to a process for producing a composition of water-absorbing polymers comprising the steps of (i) mixing (alpha1) 0.1 to 99.999% by weight, preferably 20 to 98.99% by weight, and even more preferably 30 to 98.95% by weight of monomers ethylenically unsaturated polymerized containing acid groups or their ethylenically unsaturated polymerized salts or monomers containing protonated or quaternized nitrogen, or mixtures thereof, with particular preference given to mixtures containing at least monomer s ethylenically unsaturated containing acid groups, preferably acrylic acid, (alpha2) to 70% by weight, preferably 1 to 60% by weight and more preferably from 1 to 40% by weight of ethylenically unsaturated polymerised monomers cup-limerized with (alpha1), (alpha3) 0.001 to 10% by weight, preferably 0.01 to 7% by weight and more preferably 0.05 to 5% by weight of one or more crosslinking agents, (alpha4) 0 to 30% by weight, preferably from 1 to 20% by weight and more preferably from 5 to 10% by weight of water-soluble polymers, and (alpha5) from 0 to 20% by weight, preferably 0.01 to 7% by weight and more preferably 0.05 to 5% by weight of one or more auxiliary agents, where the sum of their weights (alpha1) to (alpha5) is 100% by weight, (ii) polymerization of cross-linked free radicals to form an aqueous, water-insoluble, untreated hydrogel polymer, (iii) crush and dry the hydrogel polymer, (iv) optionally grinding and sieving the water-absorbing polymer , (v) post-cross-linking the surface of the crushed polymer hydrogel and (vi) drying and finalizing the water-absorbing polymer, in which blowing agents with a particle diameter of 100 (mi) to 900 (mi) m are added to the aqueous monomer solution, before adding the initiator and starting the polymerization of free radicals. |
