Beschreibung
Zusammenfassung:	The present invention relates to a process for producing cycloalkenamer-containing compositions, comprising the steps of: a) converting at least one cycloalkene by ring-opening metathetic polymerization to obtain a polyalkenamer-containing product mixture, and b) working up the product mixture to remove monomers and oligomers of the cycloalkenes to obtain the polyalkenamer-containing composition by extraction with CO 2 , wherein the extraction comprises at least two stages: b1) an extraction with supercritical CO 2 , then b2) an extraction with gaseous CO 2 and then b3) an extraction with supercritical CO 2 .
