Abstract

This review summarizes our and published data on the kinetics and mechanism of controlled radical polymerization of methacrylates mediated by nitroxide radicals. The reasons influencing the possibility or impossibility of the realization of radical polymerization of methyl methacrylate in the mode of reversible inhibition are analyzed. The main factors determining the specificity of the nitroxide-mediated polymerization of methacrylates are the interaction of nitroxides with growing radicals by the disproportionation mechanism, the Fischer hypereffect, a high rate of reinitiation, and an abnormally low rate of reversible termination.

氮氧化物介导的可逆抑制条件下甲基丙烯酸甲酯自由基聚合的动力学特征

摘要

本综述总结了我们和已发表的关于由氮氧自由基介导的甲基丙烯酸酯受控自由基聚合的动力学和机制的数据。分析了影响甲基丙烯酸甲酯以可逆抑制方式进行自由基聚合的可能性或不可能性的原因。决定氮氧化合物介导的甲基丙烯酸酯聚合特异性的主要因素是氮氧化合物与通过歧化机制产生的自由基的相互作用、Fischer 超效应、高再引发率和异常低的可逆终止率。
