摘要：利用歧化松香和甲基丙烯酸缩水甘油酯为原料,通过环氧开环酯化反应制得了歧化松香甲基丙烯酸甘油二酯(DR–GMA)单体,然后加入一定量的反应型稀释剂苯乙烯制得DR–GMA单体/苯乙烯共聚材料。傅立叶变换红外分析表明,DR–GMA单体已经成功制备,制备的共聚材料中DR–GMA与苯乙烯已经完全共聚;扫描电子显微镜分析表明,苯乙烯和DR–GMA形成了较好的致密交联结构共聚物;弯曲性能测试表明,共聚材料具有一定的弯曲强度,其弯曲强度可达到11.92 MPa;动态热机械分析表明,共聚物具有较高的玻璃化转变温度,其玻璃化转变温度保持在90～110℃范围内;热重分析表明,共聚材料具有优异的热稳定性,其初始分解温度高达370℃。
Disproportionated rosin methyl acrYlic acid diglyceride（DR-GMA） monomer was prepared via epoxy ring- opening esterification using disproportionated rosin and methyl acrylic glycidyl ester as raw materials. Then different concentration of reactive diluent styrene was added to prepare copolymerized materials. Fourier transform infrared spectroscopy analysis results demonstrate that target monomer has been successfully synthesized and styrene has almost entirely copolymerized with DR-GMA monomer. Scanning electron microscope analysis shows that styrene and DR-GMA form a homogeneous copolymerized system with good cross-linking structure. Flexural property test shows that the copolymer materials have relatively high flexural strength up to 11.92 MPa.Dynamic mechanical thermal analysis shows that the copolymers have high glass-transition temperatures ranged from 90℃ to 110℃. Thermogravimetric analysis results demonstrate that the copolymer materials have excellent thermal stability, as all copolymers have a high thermal initial decomposition temperature at about 370℃.
