Preparation method of hydroxyl-containing polydehydroabietic acid ester microspheres

The invention discloses a preparation method of hydroxyl-containing polydehydroabietic acid ester microspheres. The preparation method comprises the following steps: (1)mixing dehydroabietic acid/glycidyl methacrylate ester, an initiator, ethylene glycol methacrylate and toluene, and carrying out ultrasonic dispersion to obtain an oil phase; (2)adding a dispersing agent and water into the reactor,introducing nitrogen, and dissolving the dispersing agent to obtain a water phase; (3)adding the oil phase into the water phase, stirring, and heating to react; and (4)repeatedly washing, filtering and drying to obtain the hydroxyl-containing polydehydroabietic acid ester microspheres. The method disclosed by the invention is simple to operate, mild in reaction condition, green and environment-friendly, water is used as a continuous phase, the system is easy to dissipate heat, and the environmental pollution can also be reduced. 本发明公开了一种含羟基聚脱氢枞酸酯微球的制备方法：(1)将脱氢枞酸/甲基丙烯酸缩水甘油酯酯化物、引发剂、甲基丙烯酸乙二醇酯和甲苯混合，经超声分散后得到油相；(2)将分散剂和水加入
