ABSTRACT:
Described are preferred monomers including a vinylbenzyl moiety N-bonded to an alkylaminopyridinyl or pyridylimidazolyl function. Also described are preferred acid salts of such monomers. Additionally, preferred processes involving and resins formed from these preferred monomers are described. The preferred resins are highly selective for valuable heavy metal ions such as copper and demonstrate superior iron rejection values.
