Method for the preparation use of an alkoxy-functional organohydrogensiloxane oligomer using purified starting materials an duse of the oligomer
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 reaction product is distilled, treated with a treating agent, and distilled again 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.
