Abstract
Relatively high molecular weight epoxy resins cured with conventional curing agents are disclosed wherein the relatively high molecular weight epoxy resin is prepared in the presence of the curing agents. The resultant cured epoxy resin has an improvement in Tg or toughness and the mixture prior to reaction and curing is much easier to apply as a coating or in the preparation of castings, laminates and the like as compared to applications of mixtures of relatively high molecular weight epoxy resins and the curing agents.
