  • Process for the Oligomerisation of Olefins by Coordinative Chain Transfer Polymerisation
    Publication number: 20180280951
    Abstract: The present invention relates to a process for the oligomerisation of olefins, in particular ethylene, via coordinative chain transfer polymerisation (CCTP) and alkyl elimation reaction. A preferred embodiment of the invention relates to CCTP of olefins, in particular ethylene, with the use of guanidinato, amidinato or hydrocarbyl-2-pyridyl amine complexes of titanium, zirconium or lanthanides, a nickel or cobalt compound as chain displacement catalyst (CDC) and one or more chain shuttling agents (CSA) such as a main group metal alkyl.
