摘要:
The present invention provides a process for reacting A) polyorganosiloxanes which contain —Si(H) units and are of the general formula (I) with B) a mono- or pholyhydric alcohol, which comprises using small amounts of a mixture which consists of at least one acid and at least one salt of an acid as a catalyst.
摘要:
The present invention relates to branched polydimethylsiloxane-polyoxyalkylene copolymers, to a process for preparing them and to their use as anti-misting additives in silicone release coatings.
摘要:
The invention relates to a process for the dehydrogenative condensation of alcohols and siloxanes which have at least one hydrogen atom bound to a silicon atom in the molecule, wherein at least one quaternary ammonium hydroxide is used as effective catalyst in this reaction.
