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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
