PROCESS FOR THE OLIGOMERISATION OF OLEFINS BY COORDINATIVE CHAIN TRANSFER POLYMERISATION

摘要

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.
