Co-oligomerisation process

A process for the preparation of olefins of the general formula R-(CH2-CH2)p-CH=CH2 in which formula R is a hydrocarbyl group and p is an integer of at least 1, comprising reacting ethene with at least one further alpha olefin of the general formula R-CH=CH2 under oligomerisation conditions in the p...

Summary:A process for the preparation of olefins of the general formula R-(CH2-CH2)p-CH=CH2 in which formula R is a hydrocarbyl group and p is an integer of at least 1, comprising reacting ethene with at least one further alpha olefin of the general formula R-CH=CH2 under oligomerisation conditions in the presence of a catalyst system obtainable by combining a first component which is a bis(cyclopentadienyl) Group IVA metal compound containing a substituent which is attached to the metal and which is capable of reacting with a cation, and a second component which is a compound having a bulky anion containing a plurality of boron atoms and which is substantially non-coordinating under the reaction conditions and a cation, and recovering an oligomeric product comprising linear olefins of the general formula R-(CH2-CH2)p-CH=CH2, wherein the further alpha olefin(s) and ethene are present in a molar ratio of at least 1 and wherein at least one of the cyclopentadienyl groups of the metal compound is (cyclo)alkyl and/or arylalkyl substituted.
