Abstract
New ethylenebismaleimide-diamine oligoimide-II (EBMDDMCMHQ) containing 8-hydroxyquinoline as a pendent group(s) was prepared using ethylenebismaleimide-diamine oligoimide-I (EBMDDM) and 5-chloromethyl-8-hydroxyquinoline hydrochloride (CMHQ) in the presence of base catalyst. Ethylenebismaleimide-diamine oligoimide-I (EBMDDM) was prepared by the Michael addition reaction of ethylenebismaleimide (EBM) and 4,4′-diaminodiphenyl methane (DDM). The resulting oligoimide-II (EBMDDMCMHQ) was characterized by spectral techniques. Polymeric metal chelates of oligoimide-II were prepared using transition metal ions and were duly characterized. Ion-exchange properties of oligoimide-II for Fe(III), Zn(II), Ni(II), and Cu(II) metal ions were also studied by batch-equilibration method. It has good metal ion uptake capacity at varying pH ranges.
