摘要

This invention relates to a new process for the production of crosslinked, water-insoluble synthetic resins with anion exchanger properties wherein the crosslinked, water-insoluble organic polymers containing aromatic nuclei are reacted, in the presence of swelling agents for the polymer and in the presence of acid catalysts, with esters of N-hydroxyalkylamides or N-hydroxyalkylimides, and the acylamido alkylated reaction product is subsequently hydrolysed in known manner. The invention furthermore concerns new crosslinked water-insoluble synthetic resins with anion exchanger properties containing at least two aminoalkyl groups per aromatic nucleus.
