Interpretive Summary:

Technical Abstract: A simple “green” and convenient chemical modification of tung oil for maleinized tung oil (TOMA) was developed via microwave-assisted one-step maleation. The mechanism of this microwave-assisted maleation was investigated by nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC). The results clearly showed that tung oil, without initiator, can react with maleic anhydride not only via the Diels-Alder reaction, but also via free radical copolymerization. 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 and reported.
