To get more insight into the mechanism and kinetics of the RAFT process,it would be helpful to build a small molecular model reaction mimicking the RAFT process but free of a chain-propagation event. We hereby propose a model cross reaction between dithioester and alkoxyamine as a probe of the RAFT process,in which the alkoxyamine plays the role of the radical source.The generating rate of the transient alkyl radical and the nitroxyl radical can be described by the law of persistent radical effect.Thus,the advantage of the model cross reaction is that it affords a radical concentration determined by the known equation of the persistent radical effect.

为了更深入的理解RAFT聚合过程，我们构建了一个模型反应：即由烷氧基胺与双硫酯进行交换反应，烷氧基胺均裂产生的烷基自由基将会向双硫酯进行链转移，双硫酯的引入对纯烷氧基胺分解动力学造成的影响可以提供RAFT过程的许多信息。
