Process for preparing polyalkenamers for packaging applications |
| abstract |
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 CO2, wherein the extraction comprises at least two stages: b1) an extraction with liquid CO2 under the supercritical conditions and then b2) an extraction with supercritical CO2. The invention further relates to the use of these cycloalkenamer-containing compositions in the field of packaging materials, especially for food and drink. |
