摘要

(2-acryloyloxy)ethyl ester of maleopimaric acid(MA-2-HEA) with a purity of 99% was synthesized through the reaction of maleopimaric chloride with 2-hydroxyethyl acrylate with the yields near to 50%. MA-2-HEA was characterized by FT-IR spectroscopy, GC/MS, HPLC, 1H-NMR, 13C-NMR spectroscopy and DSC. The results show that (2-acryloyloxy)ethyl ester of maleopimaric acid is an acrylic monomer with anhydride group. MA-2-HEA is white crystals with melting point of 99.11 ℃ and polymerization occurs while being heated to above the boiling point The glass transition temperature of homopolymer of MA-2-HEA is about 60. 96℃. The results indicate that MA-2-HEA has a great potential to be used in epoxy resin, unsaturated resin, polyimide resin and thermoset resin, etc.%以马来海松酸为原料,草酰氯为酰基化试剂,先合成马来海松酸酰氯,再与丙烯酸-β-羟基乙基酯酯化,合成马来海松酸(β-丙烯酰氧基乙基)酯,产率为50％,质量分数为99％以上.采用FT-IR、GC-MS、HPLC、1 H-NMR、13C-NMR和DSC对其结构和性能进行分析.结果表明,马来海松酸(β-丙烯酰氧基乙基)酯是一种含有酸酐基团的白色晶体,熔点为99.11℃,加热到熔点以上可以发生自聚合反应,均聚物玻璃化转变温度约为60.96℃.马来海松酸(β-丙烯酰氧基乙基)酯具有酸酐和丙烯酰氧基团,可以应用于合成环氧树脂、不饱和树脂、聚酰亚胺树脂、热固性树脂等.
