The present invention is aimed at a process for controlled polymerization of ethylenically unsaturated monomers in the presence of heterocyclic sterically hindered alkoxyamine compounds. The intermediate N-oxyl derivatives, a composition of the N-oxyl derivatives with ethylenically unsaturated monomers and a free radical initiator, as well as a process for polymerization are also subjects of the present invention. Still further subjects of the invention are novel amine precursors and a novel process for manufacturing 5-ring heterocyclic amines.
本发明旨在提供一种在杂环立体位阻烷氧胺化合物存在下的乙烯基不饱和单体控制聚合的方法。中间体N-氧化物衍生物,N-氧化物衍生物与乙烯基不饱和单体和自由基引发剂的组合物,以及聚合的方法也是本发明的主题。本发明的其他主题是新的胺前体和一种制造5-环杂环胺的新方法。
