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: 8653162Abstract: The invention relates to a process for the preparation of a polymerization mixture suitable as a dispersant and comprising a copolymer. In the process, a vinyloxyalkylpolyether derivative is reacted with an acid monomer derivative with formation of the copolymer in the presence of a free radical polymerization initiator by free radical polymerization, the free radical polymerization taking place in a medium which contains less than 25% by weight of water and in totality more than 60% by weight of copolymer, vinyloxyalkylpolyether derivative and acid monomer derivative.Type: GrantFiled: November 25, 2009Date of Patent: February 18, 2014Assignee: Construction Research & Technology GmbHInventors: Gerhard Albrecht, Herbert Hommer, Thomas Wohlhaupter
