The usual method of preparation is by reaction of ethylene and acetic acid with oxygen and a palladium catalyst.[1]
It can be polymerized, either by itself to make polyvinyl acetate or with other monomers to prepare copolymers such as ethylene-vinyl acetate. A relatively reactive monomer due to the instability of the radical derived from VA, attempts to control the polymerization via most 'living/controlled' radical processes have proved problematic. However, RAFT (or more specifically MADIX) polymerization offers a convenient method of controlling the synthesis of PVA by the addition of a xanthate chain transfer agent.
