Soybean oil-based UV-curable coatings strengthened by crosslink agent derived from itaconic acid together with 2-hydroxyethyl methacrylate phosphate

A UV curable unsaturated monomer (IG) was synthesized from itaconic acid and glycidyl methacrylate (GMA). After its chemical structure was confirmed by Fourier Transform Infrared Spectroscopy (FT-IR) and Nuclear Magnetic Resonance (1H NMR and 13C NMR), IG was used as a crosslink agent to copolymerize with acrylated epoxidized soybean oil (AESO) and a series of UV-cured coatings were prepared. Their thermal and mechanical properties as well as...
