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. | 09-29-2011 |
