Bio-based epoxy monomers from divanillyl alcohol were successfully synthesized and fully characterized. Diglycidylether of divanillyl alcohol (DiGEDVA), triglycidylether of divanillyl alcohol (TriGEDVA) and tetraglycidyl of divanillyl alcohol (TetraGEDVA) were cured with cyclo-aliphatic diamine (IPDA) a common diamine hardener. Main properties of these vanillin-based epoxy resins were determined by DSC, TGA, DMA, tensile tests and compared to DGEBA-based reference. These bio-based systems displayed phase transition Tα from 140 to 200 °C and exhibited thermal degradation comparable to the DGEBA-based network with high char residue. Such bio-based aromatic monomers are promising substitutes to the DGEBA and can be used in high performance epoxy resin applications as bio-based aromatic polyglycidylethers.
