本文综述了文献中出现的阴离子活性中心的自发终止现象的研究结果。对聚苯乙烯,聚异戊二烯、聚丁二烯和聚甲基丙烯酸甲酯的阴离子活性中心进行了讨论和比较。通常,至少存在三种不同类型的自发终止过程:“转化”、“衰变”以及“转化”和“衰变”同时出现。这些自发终止反应可以用紫外光谱进行观察。 This article reviews the results of the spontaneous termination of anionic active sites found in the literature. The anionic active sites of polystyrene, polyisoprene, polybutadiene and polymethylmethacrylate are discussed and compared. In general, there are at least three different types of spontaneous termination processes: “Conversions,” “Decays,” and “Conversions,” and “Decays.” These spontaneous termination reactions can be observed by UV spectroscopy.
