Abstract:
1. A process for polymerizing olefin(s) in the presence of a supported catalyst system comprising contacting the supported catalyst system with monomers to form polymers, wherein the supported catalyst system is produced by contacting a supported activator, mineral oil, and a combination consisting essentially of a cyclopentadienyl and a metal compound at a temperature in the range of from 15° C. to about 75° C.; wherein the cyclopentadienyl and the metal compound are added as separate components to the mineral oil at a temperature in the range of from 15° C. to about 75° C.; wherein the metal compound is represented by the formula: wherein M is a Group 3 to 12 metal from the Periodic Table of Elements and L is selected from the group consisting of hydrogen, halogen, hydrocarbyl, alkoxide, aryoxide, carboxylate, carbodionate, amide, carbamate, and phosphide, and “x” is an integer depending on the valence state of metal; and wherein the supported activator and the combination are contacted in one slurry of a mineral oil to produce the supported catalyst system.
