A urethane acrylate derived from castor oil was synthesized using castor oil with 2-acryloyloxyethyl isocyanate and obtained in high yield. Furthermore, the obtained urethane acrylate was subjected to a UV cure reaction with polybutadiene. The UV cured film was characterized by thermal and mechanical measurements. The thermal stability of the obtained film was measured by TGA, and 20% thermal weight loss temperature at 425°C was observed. The glass transition temperature of the product was −60°C as revealed by DMA. The Young’s modulus of the product was 2.00 MPa, taken from the stress-strain curve.
