Methoxyethene CAS#107-25-5 Product Description
Vinyl methyl ether is an unsaturated ether characterized by its high chemical reactivity. Under ambient conditions, it exists as a flammable, colorless gas with a characteristic odor. Its molecular structure features both a vinyl group (-CH=CH₂) and a methoxy group (-OCH₃), contributing to its distinctive chemical properties and reactivity in various organic reactions. At standard temperature and pressure (approximately 25°C and 1 atm), it remains gaseous but can be liquefied through cooling or pressurization under appropriate conditions, forming a clear, colorless liquid.

Methoxyethene CAS#107-25-5 Product Application
1. Raw Material for PVM/MA Copolymer Production
Vinyl methyl ether can be copolymerized with maleic anhydride to produce poly(methyl vinyl ether-alt-maleic anhydride) (PVM/MA). Its derivatives are widely used in oral care products, including denture adhesives, toothpaste, and mouthwash, as well as in hair styling and skincare formulations, where they can function as film-forming, binding, and thickening agents.
2. Specialty Coatings, Inks & Adhesives
Used as a comonomer in selected polymer and resin systems, vinyl methyl ether can contribute to film flexibility and adhesion. Potential applications include peelable protective coatings, screen-printing inks, and pressure-sensitive adhesive formulations, depending on the copolymer composition.
3. Pharmaceutical Excipients & Drug Delivery
PVM/MA-based polymers and their derivatives are used in selected pharmaceutical and personal care applications. Depending on the polymer grade and formulation, they may serve as film-forming agents, binders, or components of controlled-release and topical delivery systems. Suitability for pharmaceutical use requires appropriate quality specifications and regulatory compliance.
4. Specialty Photopolymerization & Organic Synthesis
Vinyl methyl ether may be investigated or used in selected specialty polymerization systems and as a reactive building block in organic synthesis. Its suitability for cationic UV-curing formulations and cycloaddition reactions depends on the specific reaction chemistry and formulation requirements.
