Vinyl acetate, also known as VAM for vinyl acetate monomer, has the chemical formula CH3COOCH=CH2 and is a colorless liquid with a sweet flavor. Systematic names include 1-acetoxyethylene and acetic acid ethenyl ester.

The usual method of preparation is by reaction of ethylene and acetic acid with oxygen and a palladium catalyst.

It can be polymerized, either by itself to make polyvinyl acetate or with other monomers to prepare copolymers such as ethylene-vinyl acetate.
