## Abstract

A polymerization catalyst system, a method of using the polymerization catalyst system, and a polymer produced with the catalyst system. The polymerization catalyst system has a non-metallocene catalyst and a metallocene catalyst. The metallocene catalyst has the formula: wherein R1 and R2 are each independently, phenyl, methyl, chloro, fluoro, or a hydrocarbyl group.

## Claims

### Claim 1

A polymerization catalyst system comprising:
a non-metallocene catalyst; and
a metallocene catalyst of the formula:
wherein R1 and R2 are each independently, phenyl, methyl, chloro, fluoro, or a hydrocarbyl group.

### Claim 2 (depends on 1)

The polymerization catalyst system of claim 1, wherein the non-metallocene catalyst comprises a Group 15 metal-containing catalyst compound.

### Claim 3 (depends on 1)

The polymerization catalyst system of claim 1, wherein the non-metallocene catalyst comprises at least two Group 15 atoms, and wherein the non-metallocene comprises a Group 4 metal atom bound to at least one leaving group and also bound to the at least two Group 15 atoms.

### Claim 4 (depends on 1)
