CAS Number: 2768-02-7
Molecular formula: C5H12O3Si
Trimethoxyvinylsilane is also used as a as cross-linking agent and adhesion promoter in commercially-available silicone sealant product.
Trimethoxyvinylsilane is a colorless liquid.
Trimethoxyvinylsilane is bifunctional, featuring both a vinyl group and hydrolytically sensitive ethoxysilyl groups.
Trimethoxyvinylsilane is a crosslinking agent.
Applications of Trimethoxyvinylsilane:
Trimethoxyvinylsilane and the related vinyltrimethoxysilane are using as monomers and comonomer for polymers such as ethylene-vinyltrimethoxysilane and ethylene-vinyl acetate-vinyltrimethoxysilane.
Trimethoxyvinylsilanes are also used as cross-linking agents during the manufacture of cross-linked polyethylene (PEX).
The alkoxysilane moiety is reactive toward water, and in the presence of moisture, it forms silicon-oxygen-silicon bonds that cross-link the material to cure it.
Moisture-curable polymers are used as electrical insulation in some kinds of cables and for water pipe in under-floor heating installations.
Trimethoxyvinylsilanes are also used as a coupling agents or adhesion promoters for treatment of glass fibers and particulate minerals in order to form stronger bonds with resin and produce fiberglass with better mechanical properties.
Amino-functional silanes such as (3-aminopropyl)triethoxysilane and epoxy-functional silanes are used for the same purpose.
The silane group attaches to the glass substrate via covalent Si-O-Si bond, while the resin reacts with the vinyl-, amino-, or epoxy- group and binds to it.
General description of Trimethoxyvinylsilane:
Trimethoxyvinylsilane is a silane coupling agent with a silicon and hydroxyl groups that can be used to enhance the wettability and improve the superhydrophobic characteristics of different composites.
Applications of Trimethoxyvinylsilane:
Trimethoxyvinylsilane may be used to provide superhydrophobicity to different materials like TiO2, talc, kaolin, magnesium oxide nanoparticles, ammonium phosphate and PEDOT.
Trimethoxyvinylsilane modifies the surface by capping the material and creates a protective layer that is water resistant and can be used in major coating industries.

Applications of Trimethoxyvinylsilane:
Trimethoxyvinylsilane can be used as a crosslinker and a grafting agent in XLPE cables and PEX-b pipes.
Trimethoxyvinylsilane can improve mechanical and electrical properties of PE compounds.
Trimethoxyvinylsilane can act as a primer or an adhesion promoter in coating fields.
Besides adhesion, Trimethoxyvinylsilane can also promote weatherability and extend shelf life of the system.
Trimethoxyvinylsilane can be used for co-polymerization and improve dispersions of the system.
Trimethoxyvinylsilane can be used as a water scavenger in adhesive and sealant processing.
MS polymers synthesis is one of its main applications.
Elemental sulfur, a highly abundant waste product from natural gas and oil refining, can be used to create polymeric materials when reacted with unsaturated organic comonomers at elevated temperatures.
Herein, we report on the inverse vulcanization of trimethoxyvinylsilane (TMVS) particles to obtain sulfur coated TMVS-sulfur (TMVS-S) particles with a sulfur content of 18.85 wt%.
TMVS-S particles exhibit a high surface-to-volume ratio, insolubility, and can further be functionalized with N-vinylimidazole (NVIA) to incorporate N-donor ligands, known for copper(II) complexation.
Adsorption experiments with aqueous solutions of mercury(II) and copper(II) ions revealed very good distribution coefficients of TMVS-S-NVIA particles for mercury and copper remediation, showcasing possibilities arising from combining inorganic siloxane and sulfur polymers towards novel adsorbent materials derived from abundant and commercially available compounds.

Polymer modification of Trimethoxyvinylsilane:
Trimethoxyvinylsilane is used to modify polyethylene and other polymers by grafting its vinyl group to the polymer backbone using a radical initiator, such as peroxide.
This provides a polymer with pendant trimethoxysilyl groups that may be used as moisture-activated crosslinking sites via hydrolysis of the alkoxy groups followed by condensation of the resulting silanols.
Cross-linking of silane-grafted polymers
The reaction of Silane-grafted polyethylene to form a crosslinked or vulcanized polyethylene uses water to form the crosslinks.
This technology is widely used around the world for commercial applications in wire and cable insulation, tubing, and other similar uses.
The basic reaction sequence is as follows: polyethylene is reacted (grafted) with vinyltrimethoxysilane, using a peroxide initiator, in an extruder.
The grafted polyethylene is then formed into a finished product, such as cable jacketing, wire insulation, or pipe.
The forming step is usually done by a second extrusion, during which a catalyst for the moisture-cure step is added.
Finally, the formed article is exposed to moisture or hot water to cause hydrolysis of the Silane and condensation to form crosslinks via Si-O-Si bond formation.
