摘要
以甲基丙烯酸（MAA），丙烯酸丁酯（BA）和甲基丙烯酸环氧丙酯（GMA）为原料，偶氮二异丁腈（AIBN）为引发剂，十二硫醇（DT）为链转移剂，通过溶液聚合法合成了甲基丙烯酸-丙烯酸丁酯-甲基丙烯酸环氧丙酯（MAA-BA-GMA）三元共聚物，其结构和性能经^1H NMR，^13C NMR，IR，GPC，DSC和TGA表征。通过调节AIBN和DT的用量可控制MAA-BA-GMA的分子量在7900-23700。热分析数据结果表明，MAA-BA-GMA具有良好的柔性；分解温度为429℃-440℃。
Tercopolymer macromolecular modifier, methacrylic acld-butyl acrylate-glycidyl Methacry- late（ MAA-BA-GMA）, was synthesized by radical polymerization from methacrylic acid（MAA）/butyl acrylat （BA）/glycidyl methacrylate （GMA） using azobisisobutyronitrile （AIBN） as the initiator, 1-do- decanethiol（DT） as the chain transfer agent. The structure and the properties of MAA-BA-GMA were characterized by ^1H NMR, ^13C NMR, IR, GPC, DSC and TGA. The molecular weight of MAA-BA-GMA was controlled at the range of 7 900 - 23 700 by adjusting amount of AIBN and DT. The results of DSC and TGA showed that MAA-BA-GMA exhibited well plasticity and the descomposition temperatures were 429 ℃ - 440℃.
