A novel acrylic modified epoxided maleinized myrcene monomer ( AE-MYM) was prepared by D-A addition reaction, polycondensation and epoxy ring opening esterification of myrcene ( MY) with maleic anhydride, epichlorohydrin and acrylic. The molecular structure of the product was characterized with FT-IR and GPC. The UV curing behaviors of the resin monomer were also studied by using FT-IR. The results demonstrated that the target product was successfully synthesized. And the curing degree of the prepared myrcene based resin monomer could reach above 70 % within 50 s. Dynamic mechanical analysis( DMA) results showed that the glass transition temperature and the modulus of the prepared UV curing material were 65 ℃ and 4 400 MPa respectively. Tensile properties testing results demonstrated that the tensile strength of prepared UV cured material could reach above 50 MPa. All the results showed that the curing product was an excellent rigid material.
