Abstract
The novel feature in the reaction of polysiloxanes with alkoxysilanes is that fluoride ions are present as activator, such ions pref. having as their source: (i) an alkali metal fluoride; or (ii) a non-metallic cpd. esp. a tetra-alkylammonium fluoride and/or NH4F as well as trialkylamine-HF and other polyhydrofluorides or tert. org. amines.
