Technical Abstract: A new epoxy monomer from tung oil fatty acids, glycidyl ester of eleostearic acid (GEEA), was synthesized and characterized by 1H-NMR and 13C-NMR spectroscopy. Differential scanning calorimetry analysis (DSC) and FT-IR were utilized to investigate the curing process of GEEA cured by both dienophiles and anhydrides. DSC indicated that GEEA could crosslink with both dienophiles and anhydrides through Diels-Alder reaction and epoxy/anhydride ring-opening reaction. It was noticed that the Diels-Alder crosslink is much more active than the ring-opening of epoxy and anhydride in the curing process. FT-IR also revealed that GEEA successively reacted with dienophiles and anhydrides in these two crosslinking ways. Dynamic mechanical analysis (DMA) and the tensile test were applied to investigate the thermal and mechanical properties of GEEA cured by maleic anhydride, nadic methyle anhydride and 1,1'-(methylenedi-4,1-phenylene)bismaleimide, respectively. Due to the independence between the curing agents, dienophile and anhydride, a series of thermosetting polymers with various properties could be obtained by adjusting the composition of these two kinds of curing agents.
