Synthesis and Properties of Thermosets from Tung Oil and Furfuryl Methacrylate

Abstract

This work focuses on the development of cross-linked polymer from a highly unsaturated vegetable oil, tung oil (TO) and a bio-based acrylate, furfuryl methacrylate (FMA). The presence of a high degree of unsaturated carbon-carbon bonding in TO makes it a suitable precursor for polymer synthesis. Using this advantage of TO, in this work, we have synthesised a cross-linked polymer from TO and FMA through free radical polymerisation followed by Diels–Alder (DA) reaction. Successful incorporation of both of the raw materials and the two chemical reactions was shown using Fourier-transform infrared (FTIR) and Raman spectroscopy. The development of cross-linked structure was analysed through thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA).

The Prospering of Macromolecular Materials Based on Plant Oils within the Blooming Field of Polymers from Renewable Resources

“…The most recent contributions consider a prior chemical modification of tung oil with acrylic and methacrylic moieties, leading to materials of superior thermal and mechanical properties, which are readily cured by UV light [ 122 , 123 ]. A more original strategy called upon the copolymerization reaction of crude tung oil and furfuryl methacrylate under inert atmosphere, initiated by benzoyl peroxide, and the final networks were obtained in a second step based on the Diels–Alder click reaction between pendant furan moieties and residual conjugated double bonds of tung oil, which was performed under high pressure and high temperature [ 124 ]. The same acrylated tung oil was associated with styrene, and the copolymerization reaction was initiated by tert-butyl peroxybenzoate [ 125 ].…”

Cationic Copolymers of Norbornylized Seed Oils for Fiber-Reinforced Composite Applications

“…It is attributed to its high degree of unsaturation present in the linseed oil, making it highly conducive to the copolymer synthesis, from brittle plastics to elastomers. 16 , 17 Even though soybeans are among the most common food crops in America, its easy availability and low cost have enabled its market expansion to coatings, plastics, and tire industries. 18 − 23 High oleic soybean oil (HOSO) is yet another new and dynamic category of soybean oil that are essentially replacing partially hydrogenated oils, in various food and even nonfood industrial applications.…”
