Publication number: 20220049028Abstract: The present invention is directed to the use of a quaternized derivative of polyisobutylene as stabiliser in inverse emulsions like inverse emulsions used for a reverse-phase emulsion polymerisation process, e.g. for the polymerisation of acrylamide and ethylenically unsaturated cationic monomers. Such emulsions are e.g. used as flocculant for waste water treatment. The present invention is further directed to inverse emulsions comprising a quaternized derivative of polyisobutylene. The inverse emulsions have sufficiently low viscosity and sufficiently high shear stability. The present invention is further directed to an inverse emulsion polymerisation process, wherein the inverse emulsion comprises a quaternized derivative of polyisobutylene.Type: ApplicationFiled: December 6, 2019Publication date: February 17, 2022Applicants: SOLENIS TECHNOLOGIES CAYMAN, L.P., SOLENIS TECHNOLOGIES CAYMAN, L.P.Inventors: Herbert HOMMER, Gregor HERTH, Klaus MUEHLBACH, Jochen WAGNER, Rosa CORBERAN ROC

Patent number: 11015006Abstract: The present invention relates to coated polymer particles comprising a water-swellable polymer core and an essentially continuous coating encapsulating the core. The coating comprises an oxide, hydroxide or oxide hydrate of silicon, aluminum, zirconium, tin or titanium. The polymer particles do not show instantaneous swelling, when contacted with water or a water-containing liquid, but show delayed water absorption after an appropriate period of time. The coated polymer particles may be used in oil fields, in mining, for construction chemical compositions or as carrier for active substances. The coated polymer particles are prepared by a suspension coating process or a fluidized bed coating process.Type: GrantFiled: April 5, 2017Date of Patent: May 25, 2021Inventors: Peter Leidinger, Piotr Antoni Bazula, Holger Misslitz, Gregor Herth, Stefan Friedrich, Maik Schlesinger

Publication number: 20110237468Abstract: 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.Type: ApplicationFiled: November 7, 2009Publication date: September 29, 2011Inventors: Roland Reichenbach-Klinke, Marcus Guzmann, Thomas Pfeuffer, Gregor Herth, Stefan Friedrich
