Abstract

A composition includes an ionic liquid monomer having the following structure: where n is an integer from 1 to 5 and the ionic liquid monomer has a melting point less than 100° C. A method of making the ionic liquid includes providing a mixture comprising a sulfonic acid and a diamine in a solvent, and maintaining the mixture at a temperature ranging from 10 to 80° C. for a time ranging from 1 to 10 hours to form an ionic liquid monomer having a melting point less than 100° C. A method of making a polymer from the ionic liquid monomer is also provided.

Claims (5)
