Vinyl Acetate Monomer
CAS Number: 108-05-4
Vinyl acetate monomer (VAc) is the key monomer for polyvinyl acetate (PVAc) and vinyl acetate-ethylene (VAE) copolymer dispersions used in construction adhesives, interior paints, and paper coatings. It is also the precursor for polyvinyl alcohol (PVOH) and polyvinyl butyral (PVB) through saponification.

Applications
- Polyvinyl acetate (PVAc) wood and paper adhesives
- VAE copolymer dispersions for construction and decorative coatings
- Polyvinyl alcohol (PVOH) production via saponification
- Polyvinyl butyral (PVB) interlayer film manufacturing
- Textile warp sizing and finishing
Key Features
- Low Tg copolymer building block for flexible film and adhesive applications
- Easily saponified to PVOH providing water-soluble polymer intermediate
- High reactivity with ethylene for VAE dispersions with superior wet adhesion
- Ultra-low acid and water content for consistent emulsion polymerization batch quality
