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.
Claims7
A homopolymer of a water soluble, ionic, cross-linking bifunctional monomer of the formula:
- ##STR7## where X represents a univalent anion of an acid.
An electrochemical cell comprising chambers adapted to contain liquids defined by ion permeable membranes and having terminal electrodes for passing a direct current transversely through said chambers and membranes, the improvement wherein at least some of said membranes are comprised of an ion exchange, cross-linked, polymeric structure comprised essentially of a plurality of recurring units of the formula:
- ##STR8## where n is 0 to 0.75 mole fraction of m and wherein R is a member selected from a quaternary ammonium and tertiary amine group and X represents a univalent anion of an acid.
