Vinyl-triazolium monomers: Versatile and new class of radically polymerizable ionic monomers

Abstract

A set of eight functional 4-vinyl-1,2,3-triazolium monomers were synthesized using copper catalyzed azide-alkyne 2 + 3 Hüisgen cycloaddition. These vinyl-trizolium monomers readily polymerized via free radical polymerization. The physical properties of the vinyl-triazolium based poly(ionic liquid)s (PILs) are strongly dependent on the pendant functional groups. These polymers were characterized for glass transition temperature (Tg), solubility, and the thermal decomposition. The vinyl-triazolium based PILs offer an efficient route to highly functional PILs with the advantage of facile synthesis and the ability to incorporate many desirable functional moieties. © 2013 Wiley Periodicals, Inc.

In the resulting Poly(ionic liquids)s, pendant functional groups have a large effect on the solubility, Tg, and thermal stability. Copyright © 2013 Wiley Periodicals, Inc.
