具有阳离子表面活性ATRP引发剂的合成

Synthesis of Cationic Surface Active ATRP Initiators

以2-溴异丁酰溴、2-溴乙醇、6-氯-1-己醇及N,N-二甲基正十二烷基胺为主要原料,分别通过两步或三步反应合成了具有阳离子表面活性的原子转移自由基聚合(ATRP)引发剂——N-[2-(2-溴-2-甲基丙酰氧基)乙基]-N,N-二甲基正十二烷基溴化铵或N-[6-(2-溴-2-甲基丙酰氧基)己基]-N,N-二甲基正十二烷基碘化铵,其结构经1H NMR,13C NMR,IR和元素分析表征。

Two cationic surface-active ATRP initiators,N-[2-（2-bromo-2-methylpropanoyloxy）ethyl]-N,N-dimethyldodecan-1-ammonium bromide or N-[6-（2-bromo-2-methylpropanoyloxy）hexyl]-N,N-dimethyldodecan-1-ammonium iodide,were synthesized by a two-step or a three-step reaction using 2-bromoisobutyryl bromide,2-bromoethanol,6-chloro-1-hexanol and N,N-dimethyldodecyl amine as main materials.The structures were characterized by 1H NMR,13C NMR,IR and elemental analysis.
