Ethenol, also called vinyl alcohol, hydroxyethene or hydroxyethylene, is an alcohol with chemical formula C2H4O (H2C=CHOH) and CAS number 557-75-5. Normally it exists as the tautomer acetaldehyde. For this reason the thermoplastic polyvinyl alcohol (PVA or PVOH) which would be derived from this monomer, is made indirectly by polymerization of vinyl acetate and then hydrolysis of the polyvinyl acetate.
