Olefin Functional Trialkoxy Silane Silane coupling agents have the ability to form a durable bond between organic and inorganic materials to generate desired heterogeneous environments or to incorporate the bulk properties of different phases into a uniform composite structure. The general formula has two classes of functionality. The hydrolyzable group forms stable condensation products with siliceous surfaces and other oxides such as those of aluminum, zirconium, tin, titanium, and nickel. The organofunctional group alters the wetting or adhesion characteristics of the substrate, utilizes the substrate to catalyze chemical transformations at the heterogeneous interface, orders the interfacial region, or modifies its partition characteristics, and significantly effects the covalent bond between organic and inorganic materials. Alkenylsilane Cross-Coupling Agent The cross-coupling reaction is a highly useful methodology for the formation of carbon-carbon bonds. It involves two reagents, with one typically being a suitable organometallic reagent - the nucleophile - and the other a suitable organic substrate, normally an unsaturated halide, tosylate or similar - the electrophile.

Vinyltrimethoxysilane

ISI2650 - Vinyltrimethoxysilane

Applications Vinyltrimethoxysilane (cas# 2768-02-7) is a useful research chemical.

Trimethoxyvinylsilane is a chemical compound that forms a polymer matrix when combined with fatty acids. It is soluble in methanol and pluronic f127, but insoluble in water. Trimethoxyvinylsilane has been shown to be able to react with hydroxyl groups on the surface of sodium carbonate and inorganic acid. It also reacts with nitrogen atoms on the surface of sodium carbonate and inorganic acid. The kinetic data for this reaction has been determined using electrochemical impedance spectroscopy, which showed that the activation energy was 29 kJ/mol.

Trimethoxyvinylsilane is used as a chemical intermediate in the production of other fine chemicals or as a monomer in the production of vinyl functional silicone polymers. The use of Trimethoxyvinylsilane in coatings is intended to improve bonding or adhesion between organic polymers and mineral surfaces, such as pigments, fillers, and glass or metal substrates. It is used in water-based decorative coating products. It is also used as a as cross-linking agent and adhesion promoter in commercially-available silicone sealant product.
