-
A monohydroxysilane polysulfide of the formula:in which the radicals R, which may be identical or different, are hydrocarbon groups preferably comprising from 1 to 15 carbon atoms; the radicals R', which may be identical or different, are divalent linking groups preferably comprising from 1 to 18 carbon atoms; x is greater than or equal to 2. This hydroxysilane is in particular a bis-(propyidimethylsilanol) polysulfide. A process for obtaining such a hydroxysilane by alcoholysis and/or hydrolysis of a halogenated organosilane, followed by a sulfuration stage. Use of this hydroxysilane as a coupling agent.

-
Treatment of an (allyl)organosilane with silica gel in refluxing toluene brought about deallylation forming an Si-O-Si bond with the silicon on the silica gel. This Si-O-Si bond formation provides us with a new reliable method for the functionalization of a silica gel surface. Copyright
