alkyl and X represents a group such that the free radical Xe derived from X is capable of initiating polymerization of ethylenically unsaturated monomers, with the proviso that compounds A1 and A2 are excluded
Further subjects of the invention are a polymerizable composition comprising a) at least one ethylenically unsaturated monomer and b) a 1-alkoxy-polyalkyl-piperidine derivative, a process for polymerizing ethylenically unsaturated monomers, and the use of 1-alkoxy-polyalkyl-piperidine derivatives for controlled polymerization. The intermediate N-oxyl derivatives, a composition of the N-oxyl derivatives with ethylenically unsaturated monomers and a free radical initiator X•, as well as a process for polymerization are also subjects of the present invention.
本发明涉及一种含有结构元素公式(I)的1-烷氧基-多烷基哌啶衍生物,其中G1、G2、G3、G4独立地为C1-C6烷基,但至少有一个不是甲基,或者G1和G2或G3和G4,或者G1、G2、G3和G4共同形成一个C5-C12环烷基;G5、G6独立地为H、C1-C18烷基、苯基、萘基或COOC1-C18烷基,X代表一种基团,使得来自X的自由基Xe能够引发乙烯基不饱和单体的聚合,但化合物A1和A2被排除在外。本发明的另外几个方面包括:包括a)至少一种乙烯基不饱和单体和b)一种1-烷氧基-多烷基哌啶衍生物的可聚合组合物、聚合乙烯基不饱和单体的方法,以及使用1-烷氧基-多烷基哌啶衍生物进行控制聚合。本发明的中间体N-氧基衍生物、N-氧基衍生物与乙烯基不饱和单体和自由基引发剂X•的组合物,以及聚合的方法也是本发明的内容。
