Abstract
Disclosed herein are embodiments of a process which generally includes contacting i) a monomer or mixture of monomers, ii) a haloaluminate ionic liquid, and iii) one or more halide components in a reaction zone, and oligomerizing the monomer or mixture of monomers in the reaction zone to form an oligomer product. The combination of the haloaluminate ionic liquid and halide component can constitute a catalyst system which is used in embodiments of the process to produce the oligomer product.
