WebMar 9, 2015 · Abstract. A series of biobased epoxy monomers were prepared from diphenolic acid (DPA) by transforming the free acid into n-alkyl esters and the phenolic hydroxyl groups into diglycidyl ethers. NMR experiments confirmed that the diglycidyl ethers of diphenolates (DGEDP) with methyl and ethyl esters have 6 and 3 mol % of glycidyl ester. WebPhenol Formaldehyde resins make superior wood adhesives and are widely used glues for construction grade wood panels such as plywood and oriented strand boards which need to be waterproof. Part of the success of these adhesive resins is due to the formation of bonds between the glue and the phenol-like lignin which is a natural component of wood.
