Claim Text:
1. A method of producing a polyolefin polymer containing a bimodal distribution of average molecular weight polymers comprising: a) immobilizing a metallocene complex on a solid support; b) contacting the metallocene catalyst with an activator in a manner which activates 10% to 90% of the supported metallocene complex to form a first activated complex, wherein the activator is an aluminoxane defined by either of the following formulas: and the molar ratio of aluminum of the aluminoxane to the metal of the metallocene catalyst is from 25-1000; c) contacting the metallocene catalyst with an activator in a manner which activates 10% to 90% of the supported metallocene complex to form a second activated complex, wherein the activator is an aluminoxane defined by either of the following formulas: and the molar ratio of aluminum of the aluminoxane to the metal of the metallocene catalyst is from 50 to 500; or a borate compound, wherein: d) contacting the first activated catalyst and the second activated catalyst with a terminal alkene
