Abstract

Claims (28)

1 . A catalyst composition comprising:

catalyst component I comprising a single carbon or silicon atom bridged or a two carbon atom bridged metallocene compound with two indenyl groups or an indenyl group and a cyclopentadienyl group;

catalyst component II comprising a single atom bridged hafnium metallocene compound with a fluorenyl group and a cyclopentadienyl group with an alkenyl substituent;

an activator; and

optionally, a co-catalyst.

2 . The composition of claim 1 , wherein the activator comprises an activator-support, an aluminoxane compound, an organoboron or organoborate compound, an ionizing ionic compound, or any combination thereof.

3 . The composition of claim 2 , wherein the activator comprises the aluminoxane compound.

4 . The composition of claim 2 , wherein the activator comprises the activator-support, the activator-support comprising fluorided alumina, sulfated alumina, fluorided silica-alumina, sulfated silica-alumina, fluorided silica-coated alumina, fluorided-chlorided silica-coated alumina, sulfated silica-coated alumina, or any combination thereof.

5 . The composition of claim 2 , wherein the activator comprises the activator-support, the activator-support comprising a fluorided solid oxide and/or a sulfated solid oxide.

6 . The composition of claim 1 , wherein the catalyst composition comprises the co-catalyst.

7 . The composition of claim 6 , wherein the co-catalyst comprises an organoaluminum compound.

8 . The composition of claim 7 , wherein the organoaluminum compound comprises trimethylaluminum, triethylaluminum, triisobutylaluminum, or a combination thereof.

9 . The composition of claim 1 , wherein catalyst component I has two unsubstituted indenyl groups.

10 . The composition of claim 1 , wherein catalyst component I has a two carbon atom bridge.

11 . The composition of claim 1 , wherein catalyst component I has the indenyl group and the cyclopentadienyl group.

12 . The composition of claim 1 , wherein catalyst component I contains zirconium or titanium.

13 . The composition of claim 1 , wherein:

catalyst component II has a single carbon or silicon bridging atom; and

the carbon or silicon bridging atom has two substituents independently selected from H or a C 1 to C 18 hydrocarbyl group.

14 . The composition of claim 13 , wherein the alkenyl substituent is a C 3 to C 8 terminal alkenyl group.

15 . A catalyst composition comprising:

catalyst component I comprising a single silicon atom bridged or a two carbon atom bridged zirconium metallocene compound with two indenyl groups;

catalyst component II comprising a single carbon atom bridged hafnium metallocene compound with a fluorenyl group and a cyclopentadienyl group with a C 3 to C 8 terminal alkenyl substituent;

an activator; and

a co-catalyst.

16 . The composition of claim 15 , wherein:

the two indenyl groups are two unsubstituted indenyl groups; and

the single carbon atom bridge has two phenyl substituents.
