• Tung oil fatty acid
• Epoxy
• Anhydride
• Self-crosslinking

A self-crosslinking compound with epoxy groups and anhydride groups (GEMA) was successfully synthesized from tung oil fatty acid by reacting with maleic anhydride via the Diels-Alder reaction. GEMA has very good storage stability and could be cured with trace amounts of tertiary amine. This advantage avoided the nonuniformity, bubbles and insolubility during the mixing procedure of the epoxy resins and curing agents. Compared to commercial Bisphenol A epoxy resins, GEMA has relatively lower mechanical properties and thermal properties. However, in view of its renewable properties, GEMA is still a very promising bio-based epoxy which may replace bisphenol A epoxy resins in some applications. Published by Elsevier Ltd.
