本文介绍了荧光分子N-(2-菲)甲基丙烯酰胺(ANMA)作为原位监测辐射引发聚合的探针。用荧光技术测定了甲基丙烯酸甲酯(MMA)自由基聚合过程中ANMA的相对反应性。MMA自由基链末端与ANMA反应的传播速率常数与与MMA反应的反应速率常数之比为0.96。结果表明，ANMA可用于包括凝胶效应区域在内的整个反应过程的定量监测。实验结果表明，ANMA可用于甲基丙烯酸甲酯本体聚合和溶液聚合的灵敏监测。
This paper introduces the fluorogenic molecule N-(2-anthracene)methacrylamide, AnMA, employed as a probe for monitoring radiation-induced polymerization in situ. The relative reactivity of AnMA during free radical polymerization of methyl methacrylate (MMA) has been determined via fluorescence techniques. The ratio between propagation rate constants for the reaction of an MMA free radical chain-end with AnMA relative to the reaction with MMA is found to be 0.96. It is demonstrated that AnMA can be used for monitoring MMA polymerization quantitatively throughout the entire course of the reaction including the gel effect region. Results are also provided which demonstrate that AnMA can be used for sensitive monitoring of MMA polymerization both in bulk and in solution.
