There has been an increased interest in the use of vegetable oils due to low cost and large quantity production. Vegetable oils can be used as raw materials to prepare eco-friendly biodegradable polymer material. In this study, novel crosslinked polymer networks based on vegetable oils were prepared by UV photopolymerization and their mechanical properties were evaluated. The raw material used was acrylated epoxidized soybean oil (AESO.) 2,5-furan dicarboxylic acid (FDCA) was identified by the US Department of Energy as one of 12 priority chemicals for establishing the green chemistry industry of the future. It is often synthesized from 5-hydroxymethylfurfural, which in turn can be obtained from D-fructose. In this study, 2,5-furan diacrylate was synthesized from 2,5-furan dimethanol, which can be derived from FDCA to use as crosslinking agent to form crosslinked polymer networks by UV-initiated free-radical polymerization with AESO. The synthesis of acrylate derivatives was confirmed using FT-IR and 1H-NMR spectroscopic techniques. The composition of reaction mixture (the ratio of AESO to crosslinking agent) and the type of crosslinking agent (monoacrylate and diacrylate) were changed to obtain crosslinked polymer networks with various mechanical properties.
