Abstract
A water or alcohol-water soluble divinyl monomer having anion exchange group(s) and a free exchangeable anion is disclosed. These bifunctional divinyl monomers are capable of forming ion exchange materials (membranes and ion exchange resin beads) upon polymerization with added vinyl catalysts which convert them into insoluble and infusible polymers. They are also capable of being co-polymerized with other ion exchange (ion containing) monomers to give unique anion exchange resins or membranes.
Claims4

- ##STR11##
An anion exchange polymer having the following unit structure:
- ##STR12## where x represents the integer 1, y represents an integer from 0 to 1 and X.crclbar. represents an anion.
