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).
