GRAFT COPOLYMER WHOSE GRAFT CHAIN POSSESSES AN AROMATIC NITROGEN-CONTAINING HETEROCYCLE, METHOD FOR MANUFACTURING THE SAME, AND ION ADSORBENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a graft copolymer enabling efficient adsorptions and recoveries of metal ions, etc. and a method for manufacturing the same.;SOLUTION: (1) The provided graft copolymer is a graft copolymer obtained by introducing a graft chain to an ethylene-vinyl alcohol copolymer where an aromatic nitrogen-containing heterocycle has been introduced to the graft chain. (2) The provided method for manufacturing a graft copolymer comprises: a step of preparing a substrate used for grafting; and a step of obtaining a graft copolymer to which a graft chain possessing an aromatic nitrogen-containing heterocycle has been introduced by exerting an ionizing radiation onto the substrate and then (1) graft-polymerizing, with the substrate, an unsaturated monomer possessing an aromatic nitrogen-containing heterocycle or (2) graft-polymerizing, with the substrate, an unsaturated monomer possessing a functional group convertible into an aromatic nitrogen-containing heterocycle and, upon the completion of graft polymerization, converting the functional group so as to introduce thereto a graft chain possessing an aromatic nitrogen-containing heterocycle.;COPYRIGHT: (C)2014,JPO&INPIT
