Abstract
An object of the present invention is to provide a heavy metal ion scavenger having more excellent scavenging performance than previously. In order to attain this object, organic polymer materials of the present invention are characterized in that they have a polymer side chain derived from a haloalkyl-substituted styrene on the backbone of an organic polymer base and a functional group capable of forming a complex with a heavy metal ion has been introduced onto said polymer side chain. These organic polymer materials have excellent heavy metal ion scavenging performance so that they can be suitably used as heavy metal ion scavengers.
