A polyfunctional organohydrogensiloxane is prepared using a fluorinated triarylborane Lewis acid as catalyst. The polyfunctional organohydrogensiloxane may be formulated into release coating compositions. Alternatively, the polyfunctional organohydrogensiloxane may be further functionalized with a curable group to form a clustered functional organosiloxane. The clustered functional organosiloxane may be formulated into thermal radical cure adhesive compositions.

Methods for making polyfunctional organosiloxanes and compositions containing same

A composition and method can be used in the preparation of various siloxanes. The composition and method employ a fluorinated triarylborane Lewis acid, a hydrocarbonoxy-functional organosilicon compound, and a silyl hydride. The fluorinated triarylborane Lewis acid catalyzes reaction of a hydrocarbonoxy moiety (from the organosilicon compound) and a silicon-bonded hydrogen atom (from the silyl hydride) to form a siloxane bond.

Composition and method for reacting an organosilicon compound and a silyl hydride catalyzed by a fluorinated arylborane Lewis acid

A method of making a trihalodisilane, the method comprising: combining a reductive effective amount of an alkylaluminum hydride, a halodisilane comprising at least 4 halogen atoms, and a solvent at a temperature <80° C. and reducing the halodisilane to form a reaction product mixture comprising a trihalodisilane and an alkylaluminum halide.

Synthesis of 1,1,1-trichlorodisilane

A method of preparing a composition for forming a release coating is disclosed. The method comprises preparing a reaction product comprising a polyorganohydrogensiloxane compound having cyclic SiH-functional branching groups interconnected by linear polydiorganosiloxane segments (the 'branched cyclic polyorganohydrogensiloxane compound'), by combining together (A) a hydroxyl terminated polydiorganosiloxane and (B) a cyclic polyorganohydrogensiloxane, in the presence of (C) a boron containing Lewis acid and a solvent. A release coating composition including the reaction product comprising the branched cyclic polyorganohydrogensiloxane is also disclosed. The reaction product may be combined with or prepared in the presence of a polyorganohydrogensiloxane diluent and stripped of solvent to prepare the composition as a blend of the branched cyclic polyorganohydrogensiloxane and the polyorganohydrogensiloxane diluent for use in solventless-curable compositions.

Composition for preparing a release coating

Disclosed is a Silicon Precursor Compound for deposition, the Silicon Precursor Compound comprising trichlorodisilane; a composition for film forming, the composition comprising the Silicon Precursor Compound and at least one of an inert gas, molecular hydrogen, a carbon precursor, nitrogen precursor, and oxygen precursor; a method of forming a silicon-containing film on a substrate using the Silicon Precursor Compound, and the silicon-containing film formed thereby.
