| titleOfInvention | Process for preparing ring-opened polycyclic olefins for packaging applications |
| abstract | The present invention relates to a method for producing a composition comprising a ring-opened polycyclic olefin, the method comprising the steps of: a) converting at least one cyclic olefin by ring-opening metathesis polymerization to obtain a product mixture comprising the ring-opened polycyclic olefin, and b) working up the product mixture by extraction with CO to remove monomers and oligomers of the cyclic olefin, in order to obtain the ring-opened polycyclic olefin-containing composition, wherein the extraction comprises at least two Stages: b1) extraction with liquid CO2 under supercritical conditions, then b2) extraction with supercritical CO2 . The invention also relates to the use of these ring-opened polycyclic olefin-containing compositions in the field of packaging materials, in particular packaging materials for food and beverages. |
