PROCESS FOR REMOVING IRON-RESIDUES, RHODIUM- AND RUTHENIUM-CONTAINING CATALYST RESIDUES FROM OPTIONALLY HYDROGENATED NITRILE RUBBER

摘要

A process is provided for the removal of iron-residues, rhodium- and/or ruthenium-containing catalyst residues from a solution of optionally hydrogenated nitrile rubber containing such iron-residues, rhodium- and/or ruthenium-containing residues by contacting such solution with a specific functionalized ion exchange resin.
