Epoxy polymers (EPs) derived from soybean oil with varied chemical structures were synthesized. These polymers were then cured with anhydrides to yield soybean oil derived epoxy thermosets. The curing kinetic, thermal and mechanical properties were well characterized. Due to the high epoxide functionality per epoxy polymer chain, these thermosets exhibited tensile strength over an order of magnitude higher than a control formulation with epoxidized soybean oil (ESO). More importantly, thermosetting materials ranging from soft elastomers to tough thermosets can be obtained simply by using different epoxy polymers and/or by controlling feed ratios of epoxy polymers to anhydrides.
