Abstract:
The invention relates to a method of producing monodisperse amidomethylated vinylaromatic bead polymers, to ion exchangers prepared from these monodisperse amidomethylated vinylaromatic bead polymers by alkaline hydrolysis, to the method of using said monodisperse amidomethylated vinylaromatic bead polymers in the manufacture of ion exchangers and chelating resins, and also to the method of using these ion exchangers in the removal of heavy metals and noble metals from aqueous solutions or gases.
