This study aimed to synthesize a bio-based UV-curable polymer, itaconated epoxidized soybean oil (IESO), using epoxidized soybean oil (ESO) and itaconic acid (IA) as replacements for acrylic polymers. Vinyl acetate (VAc) was added to improve the polymerization rate, adhesion, and water resistance of IESO. The itaconated epoxidized soybean oil/Vinyl acetate (IESO/VAc) content was adjusted to ratios of 9:1, 7:3, and 5:5, then IESO/VAc coated paper and standalone films were produced using a UV curing system. Fourier transform infrared spectroscopy analysis confirmed a decrease in C=C bond intensity after UV curing, indicating successful radical polymerization. The adhesion test demonstrated stable adhesive performance, and the water contact angle confirmed that the coating exhibits significant hydrophobicity. In the recycling test, all samples dissolved, indicating that IESO/VAc is a bio-based material that can be chemically recycled. Consequently, IESO/VAc blends have the potential to replace fossil-based curable polymer and may be used as coatings for paper packaging.
