摘要： A polymerization process for producing polyolefins, which process employs a spray-dried catalyst composition, is provided. An example of a process is a gas phase process for making polyolefins, including: (a) forming a suspension comprising (i) a metallocene catalyst, (ii) an activator; and (iii) a support material, in a diluent; (b) spray-drying the suspension to form a catalyst composition; and (c) contacting the catalyst composition with ethylene and at least one comonomer selected from the group consisting of C4 to C8 alpha olefins in the fluidized bed of a gas-phase reactor for a time sufficient to form a polyolefin composition, wherein an external co-catalyst is absent or substantially absent from the gas-phase reactor.

摘要： The present invention provides polymerization catalyst compounds, catalyst systems including these catalyst compounds, and to their use in the polymerization of ethylene and at least one comonomer. In particular, the invention provides a catalyst system comprising a poor comonomer incorporating catalyst compound and a good comonomer incorporating catalyst compound. Preferably, the low comonomer incorporating catalyst compound is a metallocene containing at least one substituted or unsubstituted fused ring cyclopentadienyl based ligand which is substantially directed to the front of the molecule, contains a long bridging group, or which contains a methyl substitution pattern which correlates to poor comonomer incorporation. The invention also provides methods of selecting the poor comonomer incorporating metallocene to pair with the good comonomer incorporating metallocene to produce polymers that are easy to process into a variety of articles, especially polyethylene based film, having enhanced properties.
