Synthesis and Properties of UV-Curable Soybean Oil Based Polyfunctional Acrylate

With the reduction of fossil resources, renewable raw molecules have drawn a great deal of attention because of their ability to substitute for petrochemical-based materials. In this context, we synthesis a soybean oil based polyfunctional acrylate (PFA) by thiol-ene photo-click reaction and DCC catalyzed esterification in mild environment for UV-curable materials. Chemical structure was confirmed by 1H NMR and FTIR. Thermal and mechanical properties were respectively revealed by DSC, TG and TMA. All the cured films possessed excellent thermal stability and UV-curing performance, implying that they can be used for high-performance UV inks and coatings of packing industry, especially for ink-jet inks.
