Application

Vinyl Acetate is primarily used as a monomer in the production of polyvinyl acetate (PVA) and vinyl acetate-ethylene (VAE) copolymers, which are critical components in adhesives, paints, and coatings. It also serves as a precursor in the synthesis of polyvinyl alcohol (PVOH) and ethylene-vinyl acetate (EVA) resins, widely employed in packaging, textiles, and automotive applications. Researchers utilize Vinyl Acetate in emulsion polymerization studies and as a reactive intermediate in organic chemistry.
