中文摘要：

本文综述了以黄原酸酯为链转移剂的共轭乙烯基单体与非共轭乙烯基单体的RAFT自由基聚合研究进展。由于黄原酸酯的Z基团为烷氧基，使得黄原酸酯自由基中心电荷密度增加，通过共轭效应稳定双硫酯产物，因此可以很好地调控非共轭乙烯基单体的活性自由基聚合。在黄原酸酯的Z基团中引入氟原子后，它通过降低加成自由基的稳定性而不是通过稳定双硫酯产物来促进随后的断裂，可以用于共轭乙烯基单体的活性自由基聚合，用含氟的黄原酸酯化合物还可以制备共轭乙烯基单体与非共轭乙烯基单体的嵌段共聚物。

英文摘要：

The RAFI＂ radical polymerization of non-conjugated vinyl monomers and conjugated vinyl monomers mediated by xanthate are reviewed in this paper. Because the alkyloxy in xanthate （Z group） increases the electron density on central carbon atom of xanthate and stabilizes the fragmentation product, the RAFI＂ radical polymerization of non-conjugated vinyl monomers mediated by xanthate could proceed in a living way. Introducing fluorine atom into Z group of xanthate improves fragmentation of intermedia by decreasing the stabilization of intermedia, instead of stabilizing the fragmentation product. Mediated by this kind of xanthate, conjugated vinyl monomers could be polymerized in a living radical way. Moreover, block copolymers comprised of non-conjugated vinyl monomer and conjugated vinyl monomer can be prepared by fluorinated xanthate.
