以脱氢枞酸为原料,经酰氯化反应后与己二醇反应合成脱氢枞酸羟己酯,然后再用甲基丙烯酰氯进行酯化反应,合成基于脱氢枞酸的柔性单体---脱氢枞酸(2-甲基丙烯酰氧基己基)酯,得率41%。并分别采用了 FT-IR、1H NMR、13C NMR、DSC和GPC对其结构和性能进行表征。研究结果表明,脱氢枞酸(2-甲基丙烯酰氧基己基)酯在引发剂的存在下可以发生聚合反应,均聚物相对分子质量为20000~30000,玻璃化转变温度约为-21.82℃。

(2-amethcryloyloxy)hexyl ester of dehydroabietic acid (DA-2-HHMA) with a yield of 41 % was synthesized by the reaction of dehydroabietic chloride ( DA-Cl) with hexanediol, and subsequently with methacryloyl chloride. The resulting product was then characterized by using FT-IR spectroscopy, 1H NMR 13C NMR , DSC and GPC. The results showed that DA-2-HHMA could polymerize in the presence of initiator. The molecular weight of homompolymer is about 20 000 -30 000 and its glass transition temperature is around -21. 82℃.
