A method of preparing a carbosilane involves forming a grignard, lithium, or metallic reagent from a halomethyltrialkoxysilane, reacting the grignard, lithium, or metallic reagent with a dihalodihydridosilane, a trihalohydridosilane, a tetrahalosilane, a dialkoxydihydridosilane, a trialkoxyhydridosilane, or a tetraalkoxysilane to yield a carbosilane precursor, and reducing the precursor to form the carbosilane..
|Rubber compositions containing non-sulfur silica coupling agents bound to diene rubbers|
The invention provides vulcanizable rubber compound having improved tensile mechanical and dynamic viscoelastic properties. The compounds are formed by mixing an elastomer, containing unsaturated carbon-carbon bonds in its molecular structure, with a reinforcing inorganic filler silica in the presence of an alkyl alkoxysilane and a non-sulfur coupling agent that binds to the rubber backbone with an “ene” linkage or a 1,3 dipolar addition linkage.
|Water resistant compositions containing a lactone compound and an alkoxysilane|
The present invention is directed to water-resistant compositions comprising: a reaction product of at least one lactone compound and at least one alkoxysilane having at least one amino substituent; and optionally, at least one carrier. These water-resistant compositions are capable of providing or acting as a carrier for delivering benefits to various substrates, for example, keratinous substrates such as skin and hair, while at the same time, imparting durable or long lasting hydrophobicity and/or a protective barrier onto said substrates..
|Water resistant compositions containing a heterocyclic compound and an alkoxysilane|
The present invention is directed to water-resistant compositions comprising: a reaction product of at least one heterocyclic compound chosen from thiolactone compounds and their thiocarbonyl analogs, and lactam compounds and their thiocarbonyl analogs; and at least one alkoxysilane having at least one amino substituent; and optionally, at least one carrier. These water-resistant compositions are capable of providing or acting as a carrier for delivering benefits to various substrates, for example, keratinous substrates such as skin and hair, while at the same time, imparting durable or long lasting hydrophobicity and/or a protective barrier onto said substrates..
|Alkoxysilane containing polyurethane adhesive compositions containing calcium carbonate|
A composition comprising; (a.) one or more isocyanate functional prepolymers having alkoxysilane moieties; (b) a catalytic amount of one or mote compounds that catalyze the reaction of isocyanate moieties with moieties containing active hydrogen atoms; (c) carbon black; and (d) untreated calcium carbonate in an amount of about 1 to about 30 parts by weight based on the total weight of the composition.. .
|Silane-containing thermoplastic polyolefin copolymer resins, films, processes for their preparation and photovoltaic module laminate structure comprising such resins and films|
Disclosure are films based on alkoxysilane-containing polyolefin resins with reduced melt strength, photovoltaic cell laminate structures and methods for their preparation. In the disclosed alkoxysilane-containing polyolefin resin films according to the invention, reduced melt strength is provided by, among other things, using optimized silane:initiator ratios and is shown to reduce detrimental film shrinkage and provide improved photovoltaic laminate structures..
