2,6-Divanillylidene cyclohexanone

A third compound of the olefinic type, and the most promising obtained to date, is the diglycidyl ether of 2,6-divanillylidene cyclohexanone, which is produced by the conventional reaction of the diphenol with epichlorohydrin ... 

Another approach to a diglycidyl ether of this type which results in a product of improved solubility characteristics is the reaction of two moles of a pure diglycidyl ether of Bisphenol-A with one mole of 2,6-divanillylidene cyclohexanone. This results in a resin with glycidyl ether terminals which is partially soluble in ketone solvents, particularly methyl ethyl ketone. 

Further work will be necessary to produce practical paints from the 2,6-divanillylidene cyclohexanone system, but as an example of the possibilities of the olefinic approach to cleavable epoxy resins, it has been reasonably successful.
