酚氧基联烯基醚单体的原子转移自由基聚合研究

摘要

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.%Atom transfer radical polymerizations (ATRP) of phenoxyallene (PGA) 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-tolmne sulfonyl chlo-ride/CuBr/tris-[2-(dimethylamino)ethyl]amine(p-TsCl/CuBr/Me_6TREN).
