摘要：The invention generally relates to amination reactions and amination reactionproducts, and particularly to methods for aminating vinyl aromatic polymers utilizingtertiary amines. In one embodiment, the invention includes conducting an aminationreaction by combining a tertiary amine and a vinyl aromatic polymer comprising benzylchloride groups to form a reaction mixture and maintaining the pH of the reactionmixture within a designated range. In another embodiment, the invention includes anaminated vinyl aromatic polymer. In yet another embodiment, the invention includes anion exchange resin including quaternary ammonium functionality. The invention is useful inpreparing ion exchange resins suitable for a variety of applications such as the removal ofperchlorate ions from water sources and recovery of gold cyanide from mining leachsolutions.
