We present the synthesis and characterization of poly(ethyl 2-(imidazol-1-yl)acrylate) (PEImA) using free radical polymerization in various solvents with and without acids as additive. In addition, PEImA was also prepared using anionic polymerization with KOtBu as initiator in DMF and in THF at different M:I ratios. The resulting polymers of moderate dispersity were characterized by ¹H-NMR, solid state ¹³C-NMR, and size exclusion chromatography (SEC) both in water and DMAc. PEImA is an interesting highly substituted polymer as it can be modified by methylation to poly(ethyl 2-(methyl imidazolium-1-yl iodide)acrylate) PEMeImA, via ester cleavage into the polyzwitterion poly(2-(imidazol-1-yl)acrylic acid) (PImAA), and – finally - to poly(2-(methyl imidazolium-1-yl)acrylic acid) (PMeImAA) if both modification steps are carried out. We also investigated structure and solubility of these different polyelectrolytes using potentiometric titration in aqueous media.

我们介绍了在有和没有酸作为添加剂的各种溶剂中使用自由基聚合的聚2-乙基（咪唑-1-基）丙烯酸乙酯（PEImA）的合成和表征。此外，PEImA还使用阴离子聚合用KO制备吨I比：BU作为在DMF引发剂和在THF中在不同的M。通过在水和DMAc中的¹ H-NMR，固态¹³ C-NMR和尺寸排阻色谱法（SEC）对所得的中等分散性的聚合物进行表征。PEImA是一个有趣的高度取代的聚合物，因为它可以通过甲基化进行修改，以聚（2-（甲基咪唑-1-基碘化物）丙烯酸酯）PEMeImA，经由酯裂解为聚两性离子聚（2-（咪唑-1-基）丙烯酸）（PImAA），如果两个修饰步骤均最终被聚成聚（2-（甲基咪唑-1-基）丙烯酸）（PMeIAAA）被执行。我们还使用电位滴定法在水性介质中研究了这些不同聚电解质的结构和溶解度。
