Technical Abstract: In this work, a simple, “green” and convenient chemical modification of tung oil for maleinized tung oil (TOMA) was developed via microwave-assisted one-step maleation. This modifying process did not involve any solvent, catalyst, or initiator, but demonstrated the most efficiency of functionalizing plant oils: at a reaction time of 4 min, the yield of purified TOMA target product reached 94.5 wt.%. A mechanism of this microwave-assisted maleation was investigated by nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC). Moreover, three oil-based epoxides including epoxidized glycidyl ester (EGS), epoxidized soybean oil (ESO), and epoxidized octyl soyate (EOS) as well as hydroxyl-terminated polydimethylsiloxane (PDMS) were employed to react with the optimized TOMA product. Novel fully oil-based epoxy resins and silicon-containing alkyd resins were prepared. Mechanical, thermal, thermo-mechanical, and hydrophobic properties of the as-prepared epoxy and alkyd resins were evaluated.
