Abstract:
The present embodiments relate to a novel method of making quaternary ammonium polymers comprising the steps of: a) mixing 1,4-bis-dimethylamino-2-butene, triethanolamine, water and an acid; and b) introducing a 1,4-dihalo-2-butene to the mixture so as to initiate a reaction resulting in the quaternary ammonium polymer.
