摘    要:利用自主研发的实时在线监测系统,对不同聚合温度条件下,聚甲基丙烯酸甲酯(PMMA)的本体聚合过程进行实时在线监测,建立"虚拟信号值-反应时间"实时在线监测曲线.通过曲线的变化,可以清晰观察到PMMA本体聚合过程的4个阶段,即诱导期、初期、中期和后期.根据本体聚合"转化率-反应时间"S型曲线的特点,构建"虚拟信号值-反应时间-转化率"关系曲线和聚合物转化率计算公式,并提出PMMA预聚体的预测和实时在线监测方法.方法具有操作简单、实时性强、外界因素影响小和性能稳定等优点,是一种新型的实时在线分析方法.

关 键 词:Arduino    实时在线监测    聚合过程    预聚体

Abstract:The self-developed real-time online monitoring system has been applied to monitor the polymethyl methacrylate (PMMA) bulk polymerization under different polymerization temperatures online in real time. And then a real-time online curve of "virtual signal- reaction time" can be made according to the results. Through the changes in the curve, the four stages of bulk polymerization process, the induction stage, the early stage, the middle stage and the later stage can be clearly observed. According to the characteristics of the "conversion rate-reaction time" S-shaped curve of the bulk polymerization, the curve of "virtual signal-reaction time-conversion rate" and polymer conversion rate calculation formula were constructed. The real-time online monitoring and prediction of PMMA pre-polymer were proposed. This method is a new online real-time analysis method with many advantages, such as simple operation, strong real time, less influence caused by external factors, stable performance etc.
Keywords:Arduino  real-time online monitoring  polymerization process  pre-polymer
