Abstract: This invention is directed to the process and apparatus for making a polymeric membrane containing non-quaternized amine groups, with the polymer having substantially zero amounts of non-polymerized solvents. The resulting membrane is a more efficient anion membrane for recovering acid from acidic solutions by electrodialysis than the corresponding membranes containing quaternized amine groups. The membrane is made by polymerizing a monomeric mixture on a reinforcing cloth structure, which monomeric mixture is void of non-polymerizing solvents.

Abstract: The invention comprises the manufacture of cation exchangers by the copolymerization of a sulfonic acid with two other monomers such as acrylamide and n-methylolacrylamide which react simultaneously with the polymerization to form a cross-linking unit. The non-polymerizing (NP) solvent employed is water.

Abstract: The reaction of glycidyl methacrylate (GMA) with an ionogenic methacrylate ester containing amine groups of the tertiary type such as dimethylaminoethyl methacrylate (DMAEMA) in the presence of an acidic water solution produces a new and novel water soluble, ionic, cross-linking, methacrylate bifunctional monomer which is useful in the manufacture of anion exchange polymers while employing an aqueous solvent system.
