ABSTRACT:
A process for the production of a p-vinyl phenol polymer which comprises polymerizing p-vinyl phenol in the presence of (a) phenols that do not have any unsaturated side chains and (b) a polymerization accelerator; wherein water and iron are present in the polymerization reaction system so as to control formation of low molecular weight by-products which damage properties of the resulting p-vinyl phenol polymer.
