Abstract
[Notes] 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 fi lm was characterized by thermal and mechanical measurements. The thermal stability of the obtained fi lm was measured by TGA, and 20% thermal weight loss temperature at 425 ° C was observed. The glass transition temperature of the product was ¹ 60 ° C as revealed by DMA. The Young ’ s modulus of the product was 2.00MPa, taken from the stress - strain curve.
