Patent ID: 8633286

Claim:
A process for producing a polyolefin composition comprising: contacting hydrogen and ethylene monomers with a supported multi-transition-metal catalyst composition to form a polyolefin composition; wherein the supported multi-transition-metal catalyst composition comprises: (a) at least two catalyst components selected from the group consisting of: a nonmetallocene catalyst component and a metallocene catalyst component; (b) a support material that has a D 50 of less than about 30 microns, a D 90 of less than about 50 microns, and a particle size distribution having a D 90 /D 10 ratio of less than about 6; and (c) an activator; wherein the nonmetallocene catalyst component is a Ziegler-Natta catalyst component that comprises a nonmetallocene transition metal compound selected from the group consisting of Group 4 and Group 5 halides, oxides, oxyhalides, alkoxides, and mixtures thereof; and the metallocene catalyst component is represented by the formula: Cp A Cp B MX n wherein each Cp A and Cp B are the same or different and are substituted cyclopentadienyl rings, each bound to M; M is a Group 4 atom; X is selected from the group consisting of C 1 to C 6 alkyls, C 6 aryls, C 7 to C 12 alkylaryls, fluorinated C 1 to C 6 alkyls, fluorinated C 6 aryls, fluorinated C 7 to C 12 alkylaryls, chlorine and fluorine; n is 1 or 2; characterized in that at least one X is a fluorine or fluorinated hydrocarbonyl; and wherein a film made from the polyolefin has a Gel Count less than 30.
