  • Publication number: 20230056138
    Abstract: Described herein are methods for making alkenyl disiloxanes, comprising combining an alkenyl halosilane with a bis-hydrido terminated alkyl disiloxane and adding the mixture to water, an acidic aqueous solution, or a basic aqueous solution. The ratio of the alkenyl halosilane to the bis-hydrido terminated alkyl disiloxane is about 1:10 to about 10:1. The alkenyl halosilane and bis-hydrido terminated alkyl disiloxane are mixed at about 20° C. to about 45° C. In an example, no organic solvent is present. The reaction product is separated and washed with saturated NaHCO3 solution (e.g., sodium bicarbonate).

  • 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.
