ABSTRACT OF THE DISCLOSURE Polyhydroxypolyether resins are prepared by reacting in water as a dispersion an epoxide compound which has more than one 1,2-epoxy group per molecule with a dihydric phenol. The reaction is conducted in the presence of a nonionic dispersant at a temperature of about 80°C to about 100°C using, as a catalyst, an organic phosphine, a tertiary amine, or a quaternary ammon- ium or phosphonium compound. The polyhydroxypolyether resins are useful in coating compositions, molding compounds, encapsulating compositions, adhesives and the like.
