Vinyl acetate monomer (VAM) is a clear, colorless liquid with a slightly sweet and pungent odor. It's comprised of a polymerizable vinyl functional group on one end and a reactive acetate group on the other end. It is slightly miscible with water, soluble in most organic solvents and has relatively low volatility. Its vapor is heavier than air. It copolymerizes readily with a wide variety of monomers. The added acetate group imparts properties such as durability, strength, transparency and an elevated Tg.
