PROCESS FOR THE OLIGOMERISATION OF OLEFINS BY COORDINATIVE CHAIN TRANSFER POLYMERISATION AND CATALYST SYNTHESIS

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. The present invention further relates to a new method of synthesizing CCTP-catalysts. A preferred embodiment of the invention relates to CCTP of olefins, in particular ethylene, with the use of guanidinato or amidinato complexes of titanium zirconium or lanthanides, a chain displacement catalyst (CDC) such as a nickel or cobalt compound and a chain transfer agent (CSA) such as a main group metal alkyl.
