<p>The preparation of epoxy resins with high epoxy functionality that possess a lower melt viscosity and a higher glass transition temperature relative to previous epoxidized poly-p-hydroxystyrenes or epoxy novolaks is accomplished by the reaction of poly-p-hydroxystyrene polymers with epichlorohydrin and optionally a dihydric phenol in the presence of an alkaline agent which are useful in the formulation of coatings.</p> |
