<p>The invention pertains to the use of a granulate for the removal of liquid, gaseous and/or dissolved organic constituents from a process stream, said granulate consisting of dimensionally stable,porous synthetic particles with an extracting agent having a boiling point higher than 350°C at 1 bar immobilized therein, characterized in that the granulate is obtainable by suspension polymerization of a monovinyl compound in the presence of a polyvinyl compound, with at least 50% wt. % of the monomer units having an aromatic structure and with the solvent for the monomers acting both as a non-solvent for the copolymer and as an extracting agent.</p> |
