Abstract:
The present invention provides a unique and novel way of producing vinyl phenols such as poly(4-hydroxystyrene) (PHS). In this new process, 4-hydroxyphenylmethylcarbinol (HPMC) is heated under suitable conditions of temperature and pressure and for a sufficient period of time to form the poly(4-hydroxystyrene) (PHS).
