Process for preparing vinylphenol polymers & copolymers |
| abstract |
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 a basic material and for a sufficient period of time to form 4-hydroxyphenylmethylcarbinol; (b) heating 4-hydroxyphenylmethylcarbinol under suitable conditions of temperature and pressure and for a sufficient period of time to form said polyhydroxystyrene. |
