| titleOfInvention | Olefin polymerization process and catalyst system therfor |
| abstract | An olefin monomer polymerization catalyst system is described. The catalyst system comprises: (i) a vanadium catalyst having the formula: wherein: R1, R2, R3 and R4 are the same or different and each is selected from a halogen and -(NR5R6), R5 and R6 are the same or different and each is selected from the group comprising an alkyl group, an aryl group, an alkenyl group, a cycloalkyl group and a silicon-containing hydrocarbyl group, and R1 and R2 may be combined to form a cyclic moiety, with the proviso that at least one of R1, R2, R3 and R4 is -(NR5R6), or the formula: wherein: R1, R2 and R3 are as defined above, with the proviso that at least one of R1, and R3 is -(NR5R6); (ii) an organoaluminum cocatalyst; and (iii) a catalyst activator having the formula: M(R7)n wherein M is a metal selected from Group 2 and Group 12 of the Periodic Table, R7 is a C1-C12 alkyl group and n is a number equal to the valence of M. At least one of the vanadium catalyst and organoaluminum cocatalyst contains a halogen moiety. A process for polymerizing an olefin using the catalyst system is also described. |
