Abstract: The invention describes (i) reaction systems for the production of siloxanes bearing acetoxy functions, comprising a) silanes and/or siloxanes bearing alkoxy groups and/or b) silanes and/or siloxanes bearing acetoxy groups, c) silanes and/or siloxanes bearing hydroxy groups, d) optionally simple siloxane cycles and/or DT cycles, e) a reaction medium, comprising acetic anhydride, perfluoroalkanesulfonic acid and preferably acetic acid, (ii) a process for producing linear or branched siloxanes bearing acetoxy functions and also the use of same for producing polyethersiloxanes.

Abstract: Branched SiOC-linked polyethersiloxanes have the following formula (I) where R1 is an alkyl radical having 1 to 4 carbon atoms or a phenyl radical, but preferably 90% of the radicals R1 are methyl radicals; b has a value of from 1 to 10; a has a value of from 1 to 200, preferably 10 to 100, a value of from 3 to 70 when b is ?1 and ?4, or a value of from 3 to 30 when b is >4; and R2 denotes identical or different polyether radicals, but at least one radical R2 is a structural element radical of formula (II): where p=at least 2, preferably p=2-6, particularly preferably p=3.

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.
