CATALYST COMPRISING CHROMIUM AND A LIGAND COMPRISING A SUBSTITUTED CYCLOPENTADIENE AND ITS USE FOR TRIMERISING OLEFINS

摘要

A trimerisation catalyst system includes a chromium source and a ligand comprising a substituted five membered carbocyclic ring or derivatives thereof. The five membered carbocyclic ring is a substituted cyclopentadiene derivative of the general Formula, C5RnH6-n wherein each R is a substituent and n is an integer from 1 to 5. The catalyst system further includes a halogen source and a metal alkyl.
