用稳态荧光技术研究了甲基丙烯酸甲酯自由基聚合的聚合速率和凝胶效应引起的自加速。芘被用作原位聚合实验的荧光探针。对于各种聚合温度记录凝胶效应开始所需的时间。一个简单的动力学模型被用来验证实验数据。结果表明，荧光技术可用于跟踪凝胶效应的开始和聚合过程中的活化能。
The steady-state fluorescence technique was used to study the polymerization rate and the autoacceleration due to the gel effect in free-radical polymerization of methyl methacrylate. Pyrene was used as a fluorescence probe for the in situ polymerization experiments. The times required for the onset of the gel effect were recorded for various polymerization temperatures. A simple kinetic model was used to validate the experimental data. The results show that the fluorescence technique can be used to follow the onset of the gel effect and the activation energy during the polymerization processes.
