Abstract

Myrcene-based vinyl ester resin (VER) monomer was prepared via simple Diels-Alder reaction and ring-opening esterification. The molecular structure and UV curing behaviors of prepared VER monomer were characterized using FTIR analysis method. Moreover, the mechanical properties, thermal stability and hardness of its UV cured product were also investigated. FTIR analysis results demonstrated that the target myrcene-based VER monomer has been successfully synthesized. UV curing behaviors analysis showed that prepared myrcene-based VER monomer could reach ultimate cured level within 50 s. Physical properties study showed that the UV cured product has certain tensile, flexural, impact resistance properties and high hardness. TGA indicated the UV cured product had excellent thermal stability, as it showed high thermal initial decomposition temperature at 359.6 °C .
