Claim 11:
12. The method for designing a Group 4 metallocene olefin polymerization catalyst according to claim 1, wherein:
the first metallocene catalyst framework comprises two independently selected substituted or unsubstituted η5-cycloalkadienyl ligands; or
the first metallocene catalyst framework comprises two independently selected substituted or unsubstituted η5-cycloalkadienyl ligands which are bridged by a linking group of the formula (1) >ER′R2, wherein E is C or Si, R1 is hydrogen or a C1-C12 hydrocarbyl group, and R2 is hydrogen, a C1-C12 hydrocarbyl group, or a C3-C10 alkenyl group having a terminal C═C double bond, or (2) CR12CR2—, wherein R1 and R2 are selected independently from hydrogen or a C1-C6 hydrocarbyl group.
