Abstract
This invention relates to a process to polymerize olefins comprising contacting an olefin with a composition comprising the product of the combination of an activator and a transition metal compound provided that if the process occurs in the slurry phase then the activator and the transition metal compound are allowed to react for at least fifteen minutes before being contacted with the olefin.
