Method for preparing myrcenyl vinyl ester resin monomer

The invention discloses a method for preparing a myrcenyl vinyl ester resin monomer. The method comprises the following steps: adding unsaturated carboxylic acid or anhydride into a reactor, and dripping myrcene; reacting after dripping is ended, and thus obtaining myrcenyl carboxylic acid or myrcenyl anhydride; adding myrcenyl anhydride and water in an equal molar ratio into the reactor, adding epoxy chloropropane, and stirring, so that the anhydride group is fully hydrolyzed; adding a catalyst A for reacting, or adding the myrcenyl carboxylate or epoxy chloropropane into the reactor, and adding the catalyst A for reacting; reducing the temperature and adding sodium hydroxide and calcium oxide; spreading filter paper and diatomite, and performing reduced pressure suction filtration to obtain filtrate; performing rotary evaporation to remove excessive epoxy chloropropane, and thus obtaining a myrcenyl epoxy resin intermediate; adding the myrcenyl epoxy resin intermediate, a catalyst B and a polymerization inhibitor into the reactor, raising the temperature, dripping acrylic acid into the reactor, reacting after dripping is ended, and thus obtaining the myrcenyl vinyl ester resin monomer. The prepared vinyl ester resin is high in strength, high in corrosion resistance and high in weather resistance.
