  • Patent number: 4448981
    Abstract: An improved process for making an alkyl halide and organosiloxanes from a dialkyldialkoxysilane and a hydrogen halide is disclosed. Dialkyldialkoxysilane and hydrogen halide are simultaneously introduced at respective feed points into a column containing hydrogen halide under reflux in such proportions that the amount of hydrogen halide introduced into the column is at a stoichiometric excess over the dialkyldialkoxysilane. In preferred embodiments, the hydrogen halide is hydrogen chloride; the dialkyldialkoxysilane is dimethyldimethoxysilane; the alkyl halide is methyl chloride; and the organosiloxanes are predominantly of the cyclic type.

  • 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.

  • 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: 4267298
    Abstract: A method for producing triorganosilyl-end stopped diorganopolysiloxane fluids having a viscosity varying from 50 to 2,000,000 centipoise at C. comprising reacting a silanol end-stopped fluoro substituted polymer with a halogenated silane in the absence of base such that the silanol groups at the ends of the polymer are substituted by triorganosilyl groups. The advantage of the above process is that a high yield of the desired fluid is obtained.

  • Patent number: 4262107
    Abstract: A silicone rubber composition with a good shelf life and fast curing at elevated temperatures comprising a silanol end-stopped diorganopolysiloxane polymer, a silicone hydride and a rhodium complex catalyst in combination with an inhibitor compound selected from low molecular weight silanol end-stopped diorganopolysiloxanes, acetylenic compounds, olefinic carboxylic acid esters of aliphatic alcohols, alkenyl isocyanurates and mixtures of the above inhibitor compounds. The above compositions are especially suited as release coatings for plastic and cellulosic subtrates including paper.
