Web24 mei 2024 · Ionomers are polymer materials containing both neutral and ionized groups. These groups occur as pendent groups attached to the backbone of the polymer material via covalent bonding. Usually, an ionomer does not contain more than 15% ionized groups. Often, these ionized groups are carboxylic acid groups. Web7 dec. 2024 · The polymer solution was precipitated into ethyl acetate and collected via centrifugation. The polymer was air-dried after washing with additional ethyl acetate. The ionomer was converted to hydroxide form by first soaking in deionized water, then excess 1 M NaOH before being rinsed with N 2 purged deionized water.
