ABSTRACT:
Novel processes for preparing hydridosiloxane and organohydridosiloxane resins are disclosed. The processes of the invention broadly provide for the steps of contacting a silane monomer with a solid state catalyst in the presence of a reaction mixture that includes a nonpolar, e.g., hydrocarbon, solvent, and a polar solvent, e.g., alcohol and water. The process is conducted under conditions effective to catalytically convert said silane monomer into hydridosiloxanes and organohydridosiloxanes. Recovery of the products is advantageously aided by the ease of separating the solid state catalyst from the reaction mixture. Hydridosiloxanes and organohydridosiloxanes resins produced by the processes of the invention are also provided.
