以具有较高活性的酚氧基联烯基醚(POA)和对叔丁基酚氧基联烯基醚(t-BuPOA)为研究对象, 研究了不同引发
剂/配体体系对其原子转移自由基(ATRP)聚合行为的影响. 发现在2-溴代丙酸甲酯/溴化亚铜/4,4’-二庚基联吡啶(2-MBP/CuBr/dHbpy)和对甲苯磺酰氯/溴化亚铜/三-(N,N-二甲基氨基乙基)胺(p-TsCl/CuBr/Me6TREN)两种ATRP反应体系中, POA的聚合都遵循ATRP反应的机理.

关键词: 酚氧基联烯基醚, 原子转移自由基聚合, 可控自由基聚合

Atom transfer radical polymerizations (ATRP) of phenoxyallene (POA) and p-tert-butyl phenoxyallene (t-BuPOA) were studied using different initiators and ligands. It was found that the polymerization of POA followed the mechanism of ATRP both in the systems of methyl 2-bromopropanoate/CuBr/4,4’-diheptyl-2,2’-bipyridine (2-MBP/CuBr/dHbpy) and p-toluene sulfonyl chloride/CuBr/tris-[2-(dimethylamino)ethyl]amine (p-TsCl/CuBr/Me6TREN).

Key words: phenoxyallene, atom transfer radical polymerization (ATRP), controlled radical polymerization
