  • Patent number: 9006157
    Abstract: Disclosed herein are silicone wax emulsions and methods of manufacturing the same. One method of manufacturing silicone wax emulsions as disclosed herein comprises charging alpha-olefins of C-18 or greater chain length to a heating and mixing vessel along with undecylenic acid and blocking the carboxylic acid of the undecylenic acid with a compound containing a trimethylsilyl group by adding the compound in sufficient quantity and heating as a melt until blocking is complete. While maintaining a melt temperature, a silicone polymer containing methyl hydrogen siloxy units is added, followed by a hydrosilation reaction catalyst to effect a hydrosilation reaction. This results in an acid functional silicone polymer. The acid functional silicone polymer is combined with an emulsifier, and the molten combination is added to a stirred solution of alkaline agent and water that has been heated to a temperature above the silicone wax melting point. This process produces silicone wax emulsions with excellent qualities.

  • Patent number: 8933258
    Abstract: Disclosed herein are methods for a simple process to make 3-aminoorgano functional silanes and siloxanes, free from isomers, by the use of commonly available materials. One embodiment of such a method comprises reacting aminoorgano functional silanes with hexamethyldisilazane in the presence of an acidic catalyst to produce a cyclic gamma-functional aminoorganic silane and beta isomers; separating the cyclic gamma-functional aminoorganic silane and the beta isomers; and converting the separated cyclic gamma-functional aminoorganic silane to pure gamma-aminoalkylsilane or pure aminoorganic siloxane. Also disclosed herein are cyclic derivatives of gamma-functional aminoorganic silanes.

  • Patent number: 5013808
    Abstract: A method of preparing an alkoxysilane and a silicone resin includes the steps of combining a siloxane A having a first boiling point with a catalyst in a reaction vessel. A tri or tetra alkoxy functional silane monomer B is added to the vessel having a second boiling point. The contents of the vessel are heated. By a rearrangement reaction, an alkoxysilane is distilled from the vessel. The alkoxysilane has a boiling point which is lower than the mixture of the boiling points of the siloxane A, the silane monomer B and the temperature of the heated vessel. A silicone resin having alkoxy functionality and no silanol functionality is recovered from the vessel.

  • Patent number: 4797445
    Abstract: A method of preparing an organo-alkoxy substituted silicone resin including the steps of reacting an organo-silicone resin containing hydroxy terminated functional groups with an alkoxy silane in the presence of catalytic amounts of a titanate compound and incubating the mixture to derive the organo-alkoxy substituted silicone product and an hydroxylated biproduct. The organo-alkoxy substituted silicone product may be reacted with a hydroxy functional fluid in the presence of catalytic amounts of a titanate compound to derive a non-transferable, semipermanent release agent.

  • Patent number: 4622412
    Abstract: A mercapto-functional silicone fluid is prepared by hydrolyzing a mercapto-silane and an organosilane, with a weak acid. The hydrolyzate is, then, reacted in the presence of an acid with a mixture of an end-blocking polyalkylpolysiloxane and a chain-extender which is either a cyclic polysiloxane or an alkyl-terminated or hydroxy-terminated silicone fluid.
