  • Patent number: 6525130
    Abstract: A process for producing a polymerized silicone fluid comprises the steps of charging to a reaction vessel a hydroxy-terminated silicone fluid, an ethoxy-or methoxy-terminated functional silane, a basic catalyst, and a surfactant package having a cloud point of between 2 to 20° C. below the reaction temperature needed to react the functional silane with the hydroxy-terminated silicone fluid; heating the contents of the reaction vessel to a temperature that is about 2 to about 20° C. above the cloud point of the surfactant package to copolymerize the silicone fluid and functional silane; terminating the copolymerization reaction; and diluting the product with water to form an emulsion.
