Synthesis and characterization of potentially polymerizable amine-derived ionic liquids bearing 4-vinylbenzyl group

Add time:07/18/2019    Source:sciencedirect.com

The syntheses and full spectral (NMR, MS, IR), thermal (DSC) and ion chromatographic characterization of two series of amine-derived ionic liquids bearing 4-vinylbenzyl substituent and having chloride or bis(trifluoromethanesulfonyl)amide anion have been presented. The analysis of the dependence between 1H NMR chemical shift value of selected protons and the structure of cation and anion has been undertaken. Not described before in the literature results of ion chromatographic analysis of obtained compounds have been discussed. The polymerization potential of selected isolated compounds has been briefly described on the base of DSC measurements and electron beam polymerization experiments. Mentioned experiments revealed that presented ionic liquids are prone to polymerization both in solution and pure form under temperature (DSC) or electron beam irradiation to form solid polymeric products, at micrometer scale in the latter case.
