• 3) combining said treated solid oxide compound with bis(n-buytlcyclopentadieny) zirconium chloride at a temperature in a range of about 25 to about 100.degree. C. to produce a mixture;
• and
• 4) about between 1 minute and 1 hour, combining said mixture and triethylaluminum to produce said composition.

A process comprising:

• 1) contacting an oxide selected from alumina, silica-alumina, aluminophosphate, and mixtures thereof with at least one metal salt to give a metal salt infused oxide;
• 2) calcining said metal salt infused oxide to produce a calcined metal salt infused oxide;
• 3) contacting said calcined metal salt infused oxide with a treating agent selected from sulfating agents, fluoriding agents, and chloriding agents to produce a treated oxide;
• 4) combining (1) said treated oxide, (2) an organoaluminum compound selected from triethylaluminum, triisobutylaluminum, and mixtures thereof;
• and (3) an organometal compound.

A process comprising:
