An olefin polymerization process, the process comprising: contacting a catalyst composition with an olefin monomer and an optional olefin comonomer in a polymerization reactor system under polymerization conditions to produce an olefin polymer, wherein the composition of catalyst comprises a metallocene compound, an activator and an optional cocatalyst, wherein the metallocene compound has the formula: ** (See formula) ** (I); where: M is Ti, Zr, or Hf; each X independently is a monoanionic ligand; CpA is a cyclopentadienyl group with an alkenyl substituent; CpB is a fluorenyl group; and each R independently is H, a C1 to C36 hydrocarbyl group, or a C1 to C36 hydrocarbylsilyl group. |
