Polyvinyl alcohol (PVA) is a polymer that has a polymerized formula of vinyl alcohol,

CH2¼CHOH. However, the vinyl alcohol monomer has neither been isolated nor obtained in high concentration. Vinyl chloride or vinyl acetate is obtained by the addition of hydrogen

chloride or acetic acid to acetylene. Therefore, vinyl alcohol is formed by the reaction of water

with acetylene. This reaction, however, produces acetaldehyde, CH3CH¼O, and not vinyl alcohol. It is probable that vinyl alcohol is formed at a point during the reaction, but it

changes instantaneously to acetaldehyde.
