ETHYLENE OLIGOMERIZATION

The oligomerization of ethylene using a chromium catalyst having a bridged diphosphine ligand can produce a selective product distribution (to predominantly hexene or predominantly octene/hexene) when activated with an aluminoxane. The oligomerization reaction also produces polymer by product-partic...

Beschreibung
Zusammenfassung:	The oligomerization of ethylene using a chromium catalyst having a bridged diphosphine ligand can produce a selective product distribution (to predominantly hexene or predominantly octene/hexene) when activated with an aluminoxane. The oligomerization reaction also produces polymer by product-particularly when the aluminoxane is provided in a non-aromatic solvent. The present invention mitigates this problem.
