摘要

合成了4-甲基-4-[2-(萘-2-基)-2-氧乙基]碘化morpholin-4 (WSMPM)季铵盐并对其进行了表征。在347 nm (1910 L -1 L - cm-1)处的高摩尔吸收率和在蒸馏水(10-2 M)中的良好溶解度使WSMPM也可以在水溶性体系中用作有效的光引发剂。丙烯酰胺单体与WSMPM (10-3 M)和叔胺(n -甲基二乙醇胺)光聚合，单体转化为聚合物的转化率为84.4%。基于激光光解和电子自旋共振，提出了光引发机理。

4-methyl-4-[2-(naphthalene)-2-oxoethyl] morpholin-4-ium iodide as a water soluble photoinitiator

Quaternary ammonium salt namely 4-methyl-4-[2-(naphthalen-2-yl)-2-oxoethyl] morpholin-4-ium iodide (WSMPM) was synthesized and characterized. High molar absorptivity at 347 nm (1910 L･mol-1･cm-1) and good solubility in distilled water (10-2 M) allows WSMPM to be used as an effective photoinitiator also in water-soluble systems. Photopolymerization of acrylamide monomer with WSMPM (10-3 M) and a tertiary amine (N-methyldiethanolamine), resulted in 84.4% monomer to polymer conversion. Based on laser photolysis and electron spin resonance, a photoinitiator mechanism was proposed.
