]-9H-carbazole, as well as a composition of 3,6-dibromo-9-(oxiran-2-ylmethyl)-9H-carbazole with 3,4-epoxycyclohexylmethyl 3,4-epoxycyclohexane carboxylate were investigated in bulk using triphenyl carbenium salts having anions such as BF4 −, SnCl5 −, and SbCl6 −. Dark polymerizations of the carbazolyl monomers in the presence of the initiators are studied. These photoinduced polymerization reactions
摘要带有咔唑部分,9- [3-(烯丙氧基)-2-(环氧乙烷-2-基甲氧基)丙基] -9 H-咔唑,9- [3-甲氧基-2-(环氧乙烷-)的各种环氧单体的光引发阳离子聚合2-基甲氧基)丙基] -9 H-咔唑,9- [2-(环氧乙烷-2-基甲氧基)乙基] -9 H-咔唑以及3,6-二溴-9-(环氧乙烷-2)的组成基甲基)-9 ħ与3,4-环氧环己基-3,4-环氧环己烷羧酸酯-咔唑进行批量使用具有阴离子如BF三苯基碳盐调查4 - ,的SnCl 5 - ,和的SbCl 6 -。研究了在引发剂存在下咔唑基单体的黑暗聚合。这些光诱导的聚合反应给出聚合度为4-22的低聚物。讨论了光引发剂阴离子和聚合时间对聚合反应的影响。 图形概要
