Produktinformation

• Name: VINYLTRIETHOXYSILANE
• Marke: Gelest
• Beschreibung: Olefin Functional Trialkoxy SilaneSilane 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 AgentThe 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.Vinyltriethoxysilane; Triethoxyvinylsilane; TEVS; VTES; Ethenyltriethoxysilane; Triethoxysilylethylene; Triethoxy(vinyl)silaneΔHvap: 6.8 kcal/molΔHform: -463.5 kcal/molDipole moment: 1.69 debyeSpecific wetting surface area: 412 m2/gCopolymerization parameters- e,Q: -0.42, 0.028γc of treated surfaces: 25 mN/mVapor pressure, 20 °C: 5 mmSpecific heat: 0.25 cal/g/°Relative hydrolysis rate versus SIV9220.0, vinyltrimethoxysilane; 0.05Forms copolymers with ethylene for moisture induced coupling of polyethyleneCouples fillers or fiberglass to resinsSee VEE-005 for polymeric versionReacts with enamines to give (E)-β:-silylenamines, which cross-couple with aryl iodides to give β-aryl enaminesEmployed as a coupling agent, adhesion promoter, and crosslinking agentUsed in microparticle surface modification for fillersCompatible with sulfur and peroxide cured rubber, polyester, polyolefin, styrene, and acrylic based materialsFor vinylationsAvailable as an oligomeric hydrolysate, SIV9112.2Extensive review of silicon based cross-coupling agents: Denmark, S.
