Abstract
Processes of preparing freeze-dried co-catalyst compositions are provided. In an exemplary embodiment, the process includes mixing an organoaluminum compound with a modifier at low temperature to provide a modified co-catalyst composition. The process further includes further cooling the modified co-catalyst composition under reduced pressure, to provide a freeze-dried co-catalyst composition. Processes of preparing freeze-dried catalyst compositions, processes of preparing catalyst compositions, freeze-dried co-catalyst compositions, freeze-dried catalyst compositions, catalyst compositions, and processes of preparing α-olefins are also provided.
