Preparation of Chelating Ion Exchange Resins from Poly(glycidyl methacrylate) Beads

Abstract

For the purpose of preparing useful chelating resins from poly (glycidyl methacrylate) beads, the influence of pore structure of the polymer beads on the adsorption of copper( II ) ion was 'investigated.
Chelating anion exchange resins were prepared by amination of the polymer beads with triethylenetetramine. The amination was carried out easily. The chelating resins obtained from gel type polymer beads did not have good adsorption ability for copper(II) ion. It was found that the satisfactory chelating resins were prepared by the amination of macroreticular polymer beads which were obtained by suspension polymerization of glycidyl methacrylate in the presence of 2, 2, 4-trimethylpentane (50 vol% per monomer). The chelating resins obtained were moderately resistant against acid and alkali.
