To enhance the properties of acrylated epoxidized soybean oil (AESO), a comonomer of acrylated betulin (AB) is added to the matrix.

MOE and tensile strength of AESO is enhanced significantly by AB.

Adding AB in AESO coating films increase its hardness and its abrasion resistance.

The presence of AB in AESO films increase the absorption of UV light, but decrease the transparency of the coatings.

A yellowing effect is observed with the addition of AB in the AESO polymer matrix.
