Abstract: Process for producing a new class of epoxy derivative compositions involving the steps of equalizing the reactivity rate of the alpha and beta carbon atoms of an epoxy group of an epoxy containing compound by contacting said compound with carbon dioxide to generate resonance of the oxirane oxygen thereby to stabilize the velocity of the subsequent primary reaction of the compound, and passing the stabilized epoxy compound into a aqueous liquid system. The liquid system can include a dispersion of at least one other compound including a group reactive with the epoxy containing compound. According to a preferred form of the invention, an epoxy resin is passed into a reaction zone and into contact with a carbon dioxide layer to generate resonance of the oxirane oxygens of the epoxy groups of said resin.
