| Summary: | 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 relates to identifying the comonomer incorporation behavior of metallocene polymerization catalyst compounds. More particularly, the invention relates to identifying metallocene catalyst compounds which incorporate comonomer poorly. Preferably, such metallocene catalyst compounds contain at least one substituted or unsubstituted fused ring cyclopentadienyl based ligand. The invention also relates to the use of these low comonomer incorporating metallocene catalyst compounds in catalyst systems to produce polymers that are easy to process into a variety of articles, especially polyethylene based film, having enhanced properties. |
