  • Patent number: 11168181
    Abstract: A method for the preparation of an alkoxy-functional hydrogensiloxane oligomer includes reacting a polyorganohydrogensiloxane oligomer and an aliphatically unsaturated alkoxysilane in the presence of a hydrosilylation reaction and a promoter. The resulting crude reaction product is treated with a treating agent, and thereafter distilled to produce the alkoxy-functional organohydrogensiloxane oligomer. The alkoxy-functional hydrogensiloxane oligomer can be reacted with polyorganosiloxane having an aliphatically unsaturated monovalent hydrocarbon group to form a polyalkoxy-functional polyorganosiloxane. The polyalkoxy-functional polyorganosiloxane can be formulated in condensation reaction curable compositions.

    Abstract: Polysiloxane hydrolyzates are neutralized by treating polysiloxane hydrolyzates containing residual acidic constituents with carbon, and then the carbon is removed from the treated neutralized polysiloxane hydrolyzate. Some examples of polysiloxane hydrolyzates that can be treated are hydride functional polysiloxane hydrolyzates and polydiethylsiloxane hydrolyzates. The carbon neutralizing agent especially preferred is carbon derived from bituminous coal. The carbon is removed from the treated neutralized polysiloxane hydrolyzate by passing it through solid liquid separation devices such as plate and frame filter presses, polishing filters, and post filters for removing fines.
