METHOD OF POLYMERIZING AN IONIC CROSSLINKER

Abstract:

The present disclosure provides a polymerizing method where (i) an ionic crosslinker that includes a quaternary ammonium group and (ii) a non-ionic crosslinker, is polymerized in a reaction solution whose solvent is substantially a mixture of propylene glyocol (PG) and an aprotic amide-based solvent. The polymerization makes an anion-exchange polymer composition. The PG and the aprotic amide-based solvent are present in a weight ratio of from about 25:75 to about 70:30, and the reactants and solvents are present in amounts to generate the anion-exchange polymer composition with a theoretical water content from about 35% to about 60% (wt/wt).
