摘要：

采用React IRTM 4000在线红外检测装置和AutoRC(reaction calorinleter)等温反应量热器对以甲基丙烯酸十八酯、马来酸酐、苯乙烯为原料的三元共聚过程进行了反应动力学研究和热量变化研究。研究结果表明,酯基、酸酐、苯环的吸光度随时间变化基本保持不变;C=C键断裂过程中吸光度随时间的变化情况对应了三元加成共聚反应控制区;引发剂发挥引发作用需要一定的诱导期;加成聚合反应有较明显放热区,但是整个反应仍可视为相对平稳、反应温和,从而为合成工艺关键控制参数的确定和优化提供了依据。

Abstract:

The kinetics of the copolymerizing process of octadecyl methacrylate, styrene and maleic anhydride were performed by using the react IR analytical system (React IR^TM4000), and the heat flow derived from exothermic copolymerization was measured by an Auto-RC reaction calorimeter. The results showed that the absorbance of functional groups, i.e. ester, anhydride, and phenyl remained stable. The change of the absorbance with time corresponded to the ternary addition copolymerization control region when the CC bond was broken. The initiator required a certain inductiona period. There was an apparent exothermic reaction zone in the additional polymerization, while reaction was relatively stable and moderate. Therefore, this study could provide the reference for the determination and optimization of key control parameters of the synthesis process.

Key words: octadecyl methacrylate-styrene-maleic anhydride terpolymer, the react IR system, reaction calorimeter
