This invention relates to a method to support one or more catalyst compounds comprising contacting the catalyst compounds with a pretreatment agent comprising an aluminum alkyl and or an alumoxane in solution and thereafter contacting the combination with a supported activator.

Catalyst support method and polymerization with supported catalysts

This invention relates to a process to polymerize olefin(s) comprising combining a solution, slurry or solid comprising one or more bulky ligand metallocene catalyst compounds, an optional support, and or one or more activator(s) with a solution comprising one or more phenoxide catalyst compounds, and thereafter, introducing one or more olefin(s) and the combination into a polymerization reactor. This invention also relates to a polymer of ethylene wherein the polymer has a density of 0.910 to 0.930 g/cc, a melt index of 0.3 to 2.0 dg/min, and a 15 to 35 &#x3bc;m thick film of the polymer has a 45&#xb0; gloss of 60 or more, a haze of 7% or less, and a dart impact of 600 g or more.
