Abstract: The present invention provides a unique and novel way of producing vinyl phenols such as p-vinyl phenol (4-hydroxystyrene--HSM). In this new process, p-.alpha.-aminoethylphenol (AEP) is heated under suitable deamination conditions of temperature and pressure and for a sufficient period of time to form the 4-hydroxystyrene (HSM).

Abstract: The present invention provides a unique and novel way of producing 4-acetoxystyrene. In this new process, 4-hydroxystyrene is acetylated, in the presence of an acetylation agent, under suitable conditions of temperature and pressure and for a sufficient period of time to form acetoxystyrene.
