Abstract: Epoxy-containing compounds are prepared by dehydrohalogenating the reaction product of an epihalohydrin with the reaction product of a compound containing an average of more than one aromatic hydroxyl group per molecule with an alkylene oxide wherein the ratio of moles of epihalohydrin to hydroxyl groups is at least about 1.2:1. When these epoxy containing compounds are formulated into coatings, the resultant products have improved chemical resistance to acids.
