A re-epoxidized polyfunctional epoxy resin composition comprising the reaction product of : (I) an epoxidized polyfunctional epoxy resin oligomeric composition comprising a polyfunctional aliphatic or cycloaliphatic epoxy resin which has been isolated from an epoxy resin product formed as a result of an epoxidation process comprising the reaction of : (i) an aliphatic or cycloaliphatic hydroxyl-containing material; (ii) an epihalohydrin, (iii) a basic-acting substance, in the presence of (iv) a non-Lewis acid catalyst; and (v) optionally, one or more solvents; (II) an epihalohydrin; (III) a basic acting substance; in the presence of (IV) a non-Lewis acid catalyst; and (V) optionally, one or more solvents. A curable epoxy resin composition of the re-epoxidized polyfunctional epoxy resin composition and a thermoset of the curable composition is also disclosed.
