  • Patent number: 11261298
    Abstract: SiOC-based polyethersiloxanes are prepared based on linear ?,?-hydroxy group-bearing siloxanes. In a first step, ?,?-acetoxy group-bearing linear polysiloxanes are prepared. In a second step, the ?,?-acetoxy group-bearing linear polysiloxanes are converted into the desired organosiloxane units, preferably shorter organosiloxane units, wherein the thus converted organosiloxane units have ?,?-acetoxy groups. In a third step, the ?,?-acetoxy group-bearing linear polysiloxanes from step 2 react with polyetherols to give SiOC-based polyethersiloxanes.
