ABSTRACT:
An object of the present invention is to provide a separation functional material having more excellent adsorptive separation performance than previously. In order to attain this object, separation functional materials of the present invention are characterized in that they are formed by introducing a polymer side chain derived from a p-haloalkylstyrene onto the backbone of an organic polymer base and introducing a functional group onto the polymer side chain.
