摘要：以天然产物月桂烯(MY)为基体原料与马来酸酐、环氧氯丙烷和丙烯酸依次进行D-A加成、缩聚和环氧开环酯化反应制得一种新型月桂烯源乙烯基酯树脂单体(AE-MYM),并采用FT-IR、GPC对制得的产物结构进行了分析。研究表明目标产物已成功合成,相对分子质量485,且树脂单体在50 s内双键转化率可达到70%以上。动态热机械性能(DMA)分析表明制备树脂的紫外光固化产物的玻璃化转变温度达到65℃,储能模量达到4 400 MPa以上;拉伸性能测试结果表明制备的光固化产物的拉伸强度可达到50 MPa以上。以上结果分析表明制备的树脂单体固化产物是一种性能优异的刚性材料。
A novel acrylic modified epoxided maleinized myrcene monomer （AE-MYM） was prepared by D-A addition reaction, polycondensation and epoxy ring opening esterification of myreene （MY） with maleic anhydride, epichlorohydrin and acrylic. The molecular structure of the product was characterized with FT-IR and GPC. The UV curing behaviors of the resin monomer were also studied by using FT-IR. The results demonstrated that the target product was successfully synthesized. And the curing degree of the prepared myrcene based resin monomer could reach above 70 % within 50 s. Dynamic mechanical analysis（DMA） results showed that the glass transition temperature and the modulus of the prepared UV curing material were 65℃ and 4 400 MPa respectively. Tensile properties testing results demonstrated that the tensile strength of prepared UV cured material could reach above 50 MPa. All the results showed that the curing product was an excellent rigid material.
