    摘要: A process is proposed for blocking underground formations in the extraction of fossil oil and/or gas, a first step involving introducing water-absorbing particles into liquid-bearing and porous rock formations, said particles being water-swellable, crosslinked and water-insoluble polymers, said particles in the water-bearing rock formation finally preventing liquid flow through the rock layers by water absorption. This process is characterized in that the absorbing particles comprise a superabsorbent polymer with anionic and/or cationic properties and a retarded swelling action. This process, which can also be carried out in saline formation waters, is notable in that the swelling of the superabsorbents used begins no earlier than after five minutes and in that the superabsorbents are obtainable by four proposed process variants and any combination thereof. This process, which does not need a carrier liquid, is notable for its simplicity and especially the controllable retardation of the swelling action under the specific conditions of underground rock formations.

    摘要: What is claimed is a superabsorbent polymer (SAP) with anionic and/or cationic properties and retarded swelling action, which was prepared by polymerizing ethylenically unsaturated vinyl compounds. This SAP is characterized in that its swelling begins no earlier than after 5 minutes and in that it was prepared with the aid of at least one process variant selected from the group of a) polymerizing the monomer components in the presence of a combination consisting of at least one hydrolysis-stable crosslinker and at least one hydrolysis-labile crosslinker; b) polymerizing at least one permanently anionic monomer and at least one hydrolysable cationic monomer; c) coating a core polymer component with at least one further polyelectrolyte as a shell polymer; d) polymerizing at least one hydrolysis-stable monomer with at least one hydrolysis-labile monomer in the presence of at least one crosslinker. Owing to the variability of the three preparation alternatives with regard to the starting materials and the process conditions, but also owing to the possible combinations with one another, the present invention can provide superabsorbent polymers which are suitable especially for use in foams, mouldings and fibres, but also as carriers for plant growth- and fungal growth-regulating agents, and for controlled release of active ingredients, or in construction materials. The present polymers are suitable especially for use as construction material additives.
