Vinyl Acetate Monomer (VAM) for Emulsion
Número CAS: 108-05-4
Vinyl Acetate Monomer (VAM) is the highest-volume commodity monomer for emulsion polymerization, supplied at ≥99.9% purity with HQ inhibitor at 3–5 ppm for safe storage and handling. It serves as the primary monomer for PVAc homopolymer emulsions, VAE (vinyl acetate–ethylene) copolymer dispersions, and PVOH precursor polymers. High reactivity and fast propagation rate make it suitable for continuous and semi-batch emulsion processes.
