ABSTRACT:
The present invention relates to a process for preparing novel, monodisperse anion exchangers by(a) reacting monomer droplets made from monovinylaromatic compounds and polyvinylaromatic compounds, and optional porogens and/or initiators,(b) amidomethylating the resultant monodisperse, crosslinked bead polymers with phthalimide derivatives,(c) converting the amidomethylated bead polymers to aminomethylated bead polymers, and(d) alkylating the aminomethylated bead polymers.
