Acrylic acid (AA) and acrylamide (AAm) were graft copolymerized onto polyethylene powder by the preirradiation method. The PE powder grafted with both AA and AAm (PE-g-(AA-co-AAm)) rapidly adsorbed Tb ion with an efficiency higher than did PE powder grafted with AA (PE-g-AA). The complex formationn constant of Tb ion with PE-g-(AA-co-AAm) was larger than that with PE-g-AA because of the introduction of the acrylamide part decreased the steric hindrance for complexation between Tb and the carboxyl group of the graft chains.
