Abstract
Methods for preparing a catalyst system that includes contacting at least one aromatic hydrocarbon, at least one activator, at least one catalyst having a Group 3 through Group 12 metal atom or lanthanide metal atom, and at least one catalyst support to form a first mixture, are provided. Methods include reducing the amount of the aromatic hydrocarbon in the first mixture to form a second mixture having 1.5 wt % or less of the aromatic hydrocarbon based on the total weight of the second mixture. Methods may further include adding a saturated hydrocarbon to the second mixture to form a third mixture.
Claims9
A method for preparing a catalyst system comprising:
- contacting at least one aromatic hydrocarbon, at least one activator, at least one catalyst having a Group 3 through Group 12 metal atom or lanthanide metal atom, and at least one inorganic catalyst support to form a first mixture;
- reducing the amount of aromatic hydrocarbon in the first mixture to form a second mixture having 1.5 wt % or less of the at least one aromatic hydrocarbon based on the total weight of the second mixture;
- and
- adding at least one saturated hydrocarbon to the second mixture to form a third mixture, wherein the amount of the saturated hydrocarbon in the third mixture is in the range of about 0.1 wt % to about 20 wt %.
