    Assignee: General Electric Company
    Inventor: Tyrone D. Mitchell
  • Patent number: 4358575
    Abstract: A self-bonding additive for a dimedone functional one-component RTV in which the self-bonding agent is a dialkoxydisilylether functional silane.

  • Patent number: 4281145
    Abstract: A process for preparing silyl maleates, fumarates, succinates and phthalates comprising reacting an olefinic containing maleates, fumarates, succinates or phthalates with hydrogenotrichlorosilane in the presence of the platinum catalyst and then reacting the product thereof with methanol wherein the methanol is added slowly over a period of at least 6 hours to the intermediate product such that it is introduced beneath and into the liquid layer of intermediate product where most of the HCl that is formed by the reaction is removed by azeotroping it out with the methanol and water along with the HCl dissolved therein and removing the azeotrope as it being formed.
    Type: Grant

  • Patent number: 4273698
    Abstract: A self-bonding room temperature vulcanizable silicone rubber composition comprising a silanol-terminated diorganopolysiloxane base polymer, a filler, a crosslinking agent selected from carboxyl functional silanes and hydrocarbonoxy functional silanes, a curing catalyst and as the self-bonding additive a silyl maleate or a silyl fumarate or a silyl succinate. In place of the foregoing silane self-bonding additives there may be utilized as a self-bonding additive, a maleate functional polysiloxane, a fumarate functional polysiloxane or a succinate functional polysiloxane.

  • Patent number: 4238401
    Abstract: Alkoxysilyl ethers of 1,3-dicarbonyl cyclic compounds, such as methoxy tris-5,5-dimethyl-cyclohexen-2-one-3-yloxy silane can be made by effecting reaction in the presence of an acid acceptor between an alkanol, a halosilane and a 1,3-dicarbonyl cyclic organic compound, for example, 5,5-dimethyl-1,3-cyclohexane dione. The alkoxysilyl ethers are useful as vulcanizing agents for silanol terminated polydiorganosiloxanes.
    Type: Grant
    Filed: July 24, 1978
    Date of Patent: December 9, 1980
    Assignee: General Electric Company
    Inventors: James A. Cella, Tyrone D. Mitchell
  • Patent number: 4176112
    Abstract: Alkoxy substituted 1,3-dicarbonyl silyl ethers have been found to produce moisture curable organopolysiloxane compositions having optimum cure characteristics when such silyl ethers are utilized with silanol containing organopolysiloxanes. The moisture curable organopolysiloxane compositions can be used as adhesives, sealants and caulking compounds.
    Type: Grant

    Date of Patent: November 27, 1979
    Assignee: General Electric Company
    Inventors: James A. Cella, Tyrone D. Mitchell
  • Patent number: 4026880
    Abstract: A silicone compound of the formula, ##STR1## where R, R.sup.1, R.sup.2 and R.sup.6 are hydrocarbon radicals, B is selected from nitrogen, oxygen and sulfur, D is selected from a divalent hydrocarbon radical or oxygen, G is selected from various nitrogen radicals, and a, n, t, c and v are whole numbers. The above compound is eminently useful as a flocculent for colloidal biological wastes, as well as being useful as a glass sizing agent.

  • Patent number: 3965134
    Abstract: A method is provided for making silarylenesilanediol. An aqueous mixture of a dialkoxy silarylene and a water miscible organic solvent, such as acetone, is refluxed. Water is combined with the resulting mixture to effect the separation of silarylenesilanediol which can be used to make polysilarylenesiloxanes.
