PROCESS FOR PREPARING VINYLPHENOL POLYMERS AND COPOLYMERS

摘要

The present invention provides a unique and novel way of producing polyhydroxystyrene which comprises the steps of (a) heating 4-hydroxyacetophenone under suitable hydrogenation conditions of temperature and pressure in the presence of a suitable palladium catalyst and for a sufficient period of time to form 4-hydroxyphenylmethyl-carbinol; (b) heating 4-hydroxyphenylmethyl-carbinol under suitable conditions of temperature and pressure and for a sufficient period of time to form said polyhydroxystyrene.
