PURPOSE:To facilitate graft polymerization, by reacting a graft polymer, wherein a polymerizable monomer was grafted to the surface or surface layer of a base material, with hydroxylamine and converting the nitrile group in a graft chain to an amidoxim group. CONSTITUTION:After surface treatment due to low temp. plasma treatment was preliminarily applied to a base material comprising polyethylene, a polymer containing a nitrile group is reached with hydroxylamine. The reaction product is contacted with one or more of a polymerizable monomer capable of altering a nitrile group to an amidoxim group to prepare a graft polymer wherein the polymerizable monomer is grafted to the surface or surface layer of the base material. Subsequently, this graft polymer is reacted with hydroxylamine to convert the nitrile group in a graft chain to an amidoxim group to obtain a metal adsorbing material. |
