Abstract:
Disclosed are novel hafnium-based metallocene catalyst compounds with the following characteristics: 1) 4,5-dialkyl substitutions on a fluorenyl ligand, and optionally additional substitutions, 2) a cyclopentadienyl ligand, optionally with substitutions, and 3) a bridging group from group 14 of the Periodic Table. Also disclosed are catalyst systems comprising such catalyst compounds and their uses thereof, and polymers produced using such catalyst systems.

Claim (Index 2):
The syndiotactic propylene polymer of  claim 1 , wherein the compound is represented by formula (II): wherein each R 1 , R 2 , R 3 , R 6 , R 7 , R 8 , R 9 , and R 12  is independently hydrogen or a C 1  to C 10  alkyl, and wherein any of R 1  and R 2 , R 2  and R 3 , R 6  and R 7 , and R 7  and R 8  are optionally bonded together to form a ring structure; each R 4  and R 5  is independently a C 1  to C 10  alkyl; each R 13  and R 14  is independently selected from the group consisting of substituted or unsubstituted hydrocarbyl, halocarbyl, and silylcarbyl; and each X is independently a univalent anionic ligand, or two Xs are joined and bound to the metal atom to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand.
