Solvent, additive and co-catalyst effects for ethylene oligomerization catalysis

The invention is directed to catalyst systems for the oligomerization of ethylene. In some embodiments, the catalyst system includes ethylene, a solvent, and a catalyst activated with an aluminoxane co-catalyst. The system may further include an additive. Various modifications to the different reaction parameters may be made to fine-tune the reaction properties, such as productivity, activity and selectivity for a particular oligomer. For example, the solvent may be modified to include a mixture of at least two solvents. Alternatively, the co-catalyst may be modified by aging or partially fluorinating the co-catalyst. In another alternative, an additive may be included in the reaction system. Each modification to the reaction system effects a different reaction outcome, thereby enabling fine-tuning of the reaction properties by varying the modifications to the reaction system.
