Abstract: A method for forming monosubstituted diphenylsilanes is broadly provided. The method involves reacting diphenylsilane with an alcohol in the presence of a catalyst and a strong base activator. The reaction results in high selectivity to addition at only one hydrogen site.

Abstract: Porous polysiloxane microspheres may be formed using a double emulsion (W/O/W) and double reaction process. The methods generally comprise forming a first emulsion and reacting components of the emulsion phases to form reinforced hydrogen gas pockets. The first emulsion is then combined with a solvent to form a second emulsion comprising a plurality of microspheres making up the dispersed phase. The microspheres comprise the reinforced gas pockets encapsulated by a polysiloxane, which are cured and recovered. The microspheres are particularly useful as fillers for low density composite materials and sensor applications.

Abstract: A method of recovering filler material from a polymer material comprises (a) heating the polymer material to a first temperature; (b) heating the polymer material to a second temperature higher than the first temperature resulting in a pyrolyzed material; (c) elutriating the pyrolyzed material to obtain a separated mixture; and (d) filtering the separated mixture to obtain the filler material.
