Его химическая формула - C₄H₆O₂ (structural formula: CH₃COOCH=CH₂) and CAS number is 108-05-4. As a key vinyl monomer, VAc has high reactivity and is widely used in the synthesis of polymers and copolymers, playing a critical role in the production of adhesives, coatings, and textiles.

Ключевые приложения

Polyvinyl Acetate (PVAc) Synthesis: The primary application of VAc is as a monomer for producing PVAc, a thermoplastic polymer. PVAc is widely used in white latex adhesives (wood glue, paper glue), textile sizing agents, and paint binders, valued for its strong adhesion, low cost, and environmental friendliness.

Vinyl Acetate-Ethylene Copolymers (VAE): Copolymerization of VAc with ethylene produces VAE emulsions, which have excellent flexibility, water resistance, and adhesion. VAE is used in architectural coatings, non-woven fabric binders, and packaging adhesives, replacing traditional solvent-based products to reduce VOC emissions.

Other Copolymers: VAc copolymerizes with vinyl chloride (VC) to form vinyl acetate-vinyl chloride copolymers (VVCl), which improve the processing performance and low-temperature flexibility of PVC products. It also copolymers with acrylic esters to produce high-performance coatings and sealants.

Chemical Intermediates: VAc is a precursor for synthesizing polyvinyl alcohol (PVA)—PVAc is hydrolyzed to PVA, which is used in the production of synthetic fibers (vinylon), film materials, and pharmaceutical excipients. It also serves as a raw material for vinyl esters and specialty chemicals.
