“living” or controlled polymerization of a wide range of vinyl monomers. Surveying a variety of different alkoxyamine structures led to α-hydrido derivatives based on a 2,2,5-trimethyl-4-phenyl-3-azahexane-3-oxy, 1, skeleton which were able to control the polymerization of styrene, acrylate, acrylamide, and acrylonitrile based monomers. For each monomer set, the molecular weight could be controlled from 1000
对新型烷氧基胺的研究表明,硝基氧在介导各种乙烯基单体的“活性”或受控聚合方面发挥着关键作用。调查各种不同的烷氧基胺结构导致基于 2,2,5-trimethyl-4-phenyl-3-azahex-3-oxy, 1, 骨架的 α-氢化衍生物能够控制苯乙烯、丙烯酸酯的聚合、丙烯酰胺和丙烯腈基单体。对于每个单体组,分子量可以控制在 1000 到 200 000 amu 之间,多分散性通常为 1.05-1.15。基于上述单体的组合的嵌段和无规共聚物也可以用类似的控制来制备。与 2,2,6,6-四甲基哌啶氧基 (TEMPO) 相比,这些新系统代表了可在受控条件下聚合的单体范围的显着增加,并克服了与氮氧化合物介导的“活性”自由基程序相关的许多限制。单体选择和功能...
